Book excerpt: Understanding the influence of an electric field on surface properties of liquids is of importance from both fundamental and practical standpoints. Charged or electrified drops currently play a key role in various applications, ranging from microfluidic devices to agricultural treatments. Nevertheless, the effects of the electric field on surface properties of drops are not understood yet, mainly due to the lack of reliable tools and methodologies to measure such effects.In this research, novel methodologies are developed that allow study of shape, surface tension, and contact angle of drops in the electric field: Automated Polynomial Fitting (APF) is a high-accuracy technique to determine contact angle of drops. It is applicable quite universally, and hence can be employed to measure the effect of the electric field on contact angles. Axisymmetric Drop Shape Analysis-Electric Fields (ADSA-EF) is a sophisticated drop-shape shape technique developed to study surface tension of drops in the electric field. ADSA-EF can also measure surface tensions in the absence of gravity; hence it is an ideal tool for microgravity research. Axisymmetric Liquid Fluid Interface-Electric Fields (ALFI-EF) is a side product of this research that can predict and simulate drop shapes in the electric field.In addition, two sets of ADSA-EF experiments were conducted in reduced-gravity using facilities provided by the Canadian Space Agency (CSA). In general, the measurements in the reduced-gravity condition agreed well with the previous ground-based measurements. The results suggested that gravity has no significant influence on the surface tension, as expected.Extensive experimental work was performed using the new methodologies. The correlation between thermodynamic contact angles and the electric field was determined for the first time, using APF. It was found that contact angle of polar liquids increases in the electric field (depending on the size of the molecules), whereas non-polar liquids remain unaffected by the field. The observations were interpreted in terms of liquid interfacial tensions, using thermodynamic relations. ADSA-EF experiments showed similar increase in liquid surface tensions; furthermore, they revealed a second-order correlation between the surface tension of conducting liquids and the electric field.

Available in PDF, EPUB and Kindle. Book excerpt: The generalized theory of capillarity identifies line tension as a natural and necessary extension of analysis for the systems with multi-phase boundary curves. Theoretically, finding an estimate for line tension is very complicated. Modeling of molecular interactions almost always requires significant simplifications which would cause considerable uncertainty in the resulting values. Experimentally, line tension is typically small and hence much more difficult to measure than surface tension. A review of the literature shows that there is little consensus among researchers with respect to both sign and magnitude of line tension. Our preferred method to determine line tension for solid-liquid-vapor systems takes advantage of dependence of contact angles on the drop size according to the modified Young equation (Eq. 2.22). Using a sensitive and accurate contact angle and drop size measurement methodology, i.e., Axisymmetric Drop Shape Analysis (ADSA), a large number of contact angle data were produced, i.e., 27, solid-liquid-vapor systems were studied. Potential artifacts that may effect the observed drop size dependence of contact angles including contortions of the three-phase line, solid surface deformation, thin film effect, and heterogeneity of the solid surface, were considered. They all proved insignificant either by the use of models developed to describe and analyze the effect of the particular feature, or by thermodynamic reasoning, or the use of available literature (see section 4.4). It was established that line tension was positive for all of the systems studied. The magnitude of line tension determined ranges from below from 10-7 J/m for systems with low contact angles to 10-4 J/m for the high energy system studied (the range reflects mainly the material properties such as intermolecular forces). Exploratory steps taken to examine line tension behavior near the wetting transition suggested that the line tension decreases as the contact angle decreases and perhaps vanishes at complete wetting. A high energy system, i.e., liquid tin on a silica surface, was also studied. The seemingly large line tension value obtained, i.e., 10-4 J/m, should not be entirely surprising, as it was found that there exists a positive correlation between line tension and solid-liquid interfacial tension.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of fluid mechanical, thermal and physico-chemical aspects of drop-surface interactions. Basic physical mechanisms pertaining to free-surface flow phenomena characteristic of drop impact on solid and liquid surfaces are explained emphasizing the importance of scaling. Moreover, physico-chemical fundamentals relating to a forced spreading of complex solutions, analytical tools for calculating compressibility effects, and heat transfer and phase change phenomena occurring during solidification and evaporation processes, respectively, are introduced in detail. Finally, numerical approaches particularly suited for modeling drop-surface interactions are consisely surveyed with a particular emphasis on boundary integral methods and Navier-Stokes algorithms (volume of fluid, level set and front tracking algorithms). The book is closed by contributions to a workshop on Drop-Surface Interactions held at the International Centre of Mechanical Sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Management of bubbles/drops, and solid particles is a major task in many industrial processes. For almost all conventional applications, the gravitational force is predominantly used to control and manipulate their motion. In the cases where the gravitational force can no longer serve the purpose, particle control by electric field is a promising alternative. Thus, the electrohydrodynamic phenomenon, which deals with the interaction of fluid flow and electric field, is being studied in many physical, chemical, and engineering disciplines. Some of the prominent applications are microelectromechanical devices, enhancement of heat and mass transfer, and electroseparation devices (electrophoresis units, electrodialysis cells, and electrically driven desalters). In this thesis, the dynamics of drops suspended in an electric field were studied using Direct Numerical Simulations (DNS). The Navier-Stokes equation and the electrostatic equation were solved for the fluid inside and outside the drop. Several sets of simulations were performed concerning the dynamics of a single drop. The single bubble simulations captured the transient behavior of the drop, flow, and the electric field toward the steady state. Low surface tension drops readily deformed to oblate or prolate shapes while drops having high surface tension remained circular or went through rebound before reaching a steady state. The multibubble simulations showed the significance of the relative magnitude of the conductivity ratio (R) and the permittivity ratio (S), of the fluid drop to the ambient fluid, in the microstructure formation of the drops. When S > R , the drops tended to deform to oblate shapes and accumulate in the middle of the domain. For S

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The electrowetting effect has emerged as an important research topic in recent years. Manipulation of droplets by electric fields has been extensively studied employing different setups, the most common being the configuration in which the electric field is created inside the droplet. However, such a configuration has been mostly employed using conductive liquids, whereas non-conductive droplets have been barely tested under the effect of an electric field using this setup. On the other hand, the influence of an electric field on the shape of a droplet has also been of considerable interest using an alternative configuration in which the electric field is applied between two electrodes with no contact with the drop – the Taylor cone configuration. However, the effects observed employing this last setup are rather different to those obtained using the aforementioned design. While the most important effect in those experiments in which the electric field is created inside the drop is the reduction of the contact angle, the main effect found using the second configuration is the droplet elongation in the electric field direction. In order to demonstrate if dielectric and almost perfectly wetting liquid droplets are affected in the same way as other fluids already tested, the effect of an electric field on the shape of an HFE-7500 droplet has been examined under two different experimental setups by means of interferometric techniques. For the setup where the internal electric field is created, no statistically relevant reduction was measured. Nevertheless, shape deviations have been found at a certain distance of the wire through which the electric field is applied. Moreover, the existence of such deviations depends strongly on the AC frequency. Regarding the second design, it should be mentioned that the initial parallel plate design was working correctly for water+salt droplets. However, no remarkable effects were observed applying strong electric fields of up to 10 kV/cm on HFE-7500 droplets. With the goal of increasing the field strength, two improvised configurations of a metal ring and a needle as a counter-electrodes have also been implemented. In these cases, a strong non-uniform electric field was created which did lead to shape changes of the droplets.

Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of this thesis is the development of a new methodology of contact angle measurement called ADSA-NA (Axisymmetric Drop Shape Analysis - No Apex) that analyzes drop shape configurations with no apex. Thus ADSA-NA facilitates contact angle measurements on drops with a capillary protruding into the drop. This development is desirable because the original ADSA has some limitations for contact angle measurement, and there is a need for the improvement of the accuracy of contact angle measurement.Computational as well as design aspects of ADSA-NA were scrutinized in depth, well beyond the level of scrutiny in the original ADSA. On the computational side, the results obtained from one and the same drop image were compared using different gradient and non-gradient edge detection strategies and different gradient and non-gradient optimization methods. It was found that the difference between the results of different edge detection strategies is minimal. It was also found that all the optimization methods yield the same answer with eight significant figures for one and the same image. The determination of the location of the solid surface in the drop image was also further refined.On the design side, the effect of controllable experimental factors such as drop height and drop volume on the accuracy of surface tension measurement was studied. It was shown that drop height is the dominant experimental factor, and larger drop heights yield lower surface tension errors.To develop ADSA-NA, a new reference point other than the apex and a new set of optimization parameters different from those of ADSA had to be defined. The three main modules of ADSA had also to be modified; the image analysis, the numerical integration of the Laplace equation for generating theoretical curves, and the optimization procedure. It was shown that ADSA-NA significantly enhances the precision of contact angle and surface tension measurements (by at least a factor of 5) compared to those obtained from sessile drops using ADSA.

Book excerpt: A method of estimating the contact angle of a sissle drop on a clean, level surface, is developed for drops whose profiles are so low that the contact angles are too small to measure. A simple geometric relationship between the drop's volume and its contact angle is demonstrated, both mathematically and by experiment, and is shown to hold within the limits defined by the conditions.

Available in PDF, EPUB and Kindle. Book excerpt: A simple and accurate technique has been developed for measuring dynamic surface tension. The new technique is based on growing a drop at the end of a fine capillary into another immiscible fluid and can follow the changes in tension at a freshly formed interface during its entire period of evolution. When the relative importance of the surface tension force is large compared to gravitational and viscous forces, shapes of growing drops are sections of spheres and the difference in pressure between the interior and the exterior of the drop {triangle}p is related to the surface tension [sigma] and the radius of curvature R by the static Young-Laplace formula {triangle}p = 2[sigma]/R. In contrast to related work, the new technique can determine the surface tension of an interface with a surface age of a few to tens of milliseconds by measuring transient drop shapes and pressures in 1/6 to 1 millisecond. The capabilities of the new method are demonstrated by performing tension measurements on liquid systems that do not exhibit dynamic surface tension as well as ones that exhibit significant dynamic tension effects. Tension measurements made with surfactant-laden solutions show that variation of surface tension is nonmonotonic in time. In such systems, the dynamic behavior of surface tension is shown to depend upon both the rate of interfacial dilatation and that of surfactant transport. A maximum in the surface tension is attained when the lowering of the surfactant concentration on the drop interface due to its dilatation is balanced by the addition of fresh surfactant to the interface by convection and diffusion.

Book excerpt: "Microfluidics (uF) is the science of manipulating and controlling the fluids usually in the range of microliters (10-6L) to picolitres (10-12L). Physical parameters, such as surface tension and contact angle do not play a significant effect on macro scale but play a crucial role at the microscopic level. Microfluidics is viewed as an essential tool for life science research and flexible electronics. A deeper understanding of physical parameters of microfluidics would result in more efficient and lower cost devices (‘Lab-on-a-Chip’ devices) and foldable electronics. In short, the concepts of microfluidics can be used to reduce the cost, size, and ease of usage in a wide variety of futuristic products. In our study we are going to explore the effects of electric fields on a particle transport in evaporating droplet and deposition patterns left behind evaporating droplets. We will be studying droplets evaporating on ‘Electrowetting on Dielectric’ (EWOD) devices where the droplet is separated from the active electrode by dielectric layers. These types of devices are relevant in a variety of applications such as medical diagnostics and optics. We believe that understanding this phenomenon will impact printing and the development of flexible electronics. This work will further the understanding of transport and deposition of particles in evaporating droplets under applied electric field by understanding the effects of particle concentrations and different dielectric layer. Previous works have demonstrated that particle transport in evaporating droplets and their resultant deposition patterns can be altered under the presence of the electric fields. Applied electric fields have potential to provide real-time control of the particle transport in evaporating droplets by allowing an instantaneous control of the contact line dynamics, electrophoretic manipulation of particles inside the droplet, changes in interface shape, dielectrophoretic manipulation and particle motion inside the droplet due to forces induced by the electric field and evaporation. Our work is going to provide a deeper insight into the effects of DC electric fields on droplets with varying particle concentrations on different dielectric layer. We will better understand the effects of changing the variables (i.e., hydrophobicity, polarity and particle concentration) under applied DC electric field."--Abstract.
