Book excerpt: Sessile droplets are widely found in day to day life: it might be a coffee spilt, rain onto a waterproof raincoat or again, water falling onto a cooking plate. However, despite the vast number of studies devoted to droplets for almost half a century, the fundamental phenomenon of the evaporation of sessile droplets is still a field that attracts a high level of interest due to its wide applicability and the development of new visualisation techniques or new types of complex fluids. This experimental study is focused two distinct aspects:- The evaporation of pure fluids has allow to study hydrothermal waves that appear in the droplets of volatile fluids during phase change. The influence of the type of fluid --different alcohols and alkanes-- and the gravity levels --Terrestrial, Lunar and Martian-- is investigated to have a better understanding of the flow motion inside droplet. Moreover, the use of different gravity levels allows to experimentally evidence the contribution of the atmospheric convective transport to sessile droplet evaporation. This investigation has allowed to develop an empirical model to take account of natural convection which greatly increases the evaporation rate in the quasi-steady diffusion-controlled evaporation model.- If complex fluids exhibit an evaporation dynamic similar to pure fluid, other mechanisms come into play, such as gelation, particles organisation and cracks formation. Wetting and different functional groups on the particles graphs will be studied in relation to the final pattern of cracks.

Book Synopsis Modeling Sessile Droplet Dynamics in Channel Flow by : Amirreza Golpaygan
Download or read book Modeling Sessile Droplet Dynamics in Channel Flow written by Amirreza Golpaygan and published by . This book was released on 2007 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamics of a sessile droplet in channel flow is studied numerically. The numerical model uses one set of the governing equations combined with a volume tracking method on a fixed structured mesh to model the simultaneous movement of mass and momentum across cell boundaries. Surface tension is modeled as a body force acting on the fluid near the free surface. Two dimensional sessile droplet deformation and channel flow structures are discussed for both pinned and unpinned droplets. The effects of having a fixed contact line on the deformation and breakup of a droplet are investigated. A characteristic length is defined to compare droplet deformation due to changes in the surface tension, viscosity and density ratios. Among theses parameters, the surface tension is found to be the most important one in determining the mobility of the droplets. A breakup criterion is obtained in terms of droplet Reynolds and Capillary numbers. Next, dynamics of two spaced sessile droplets in a channel flow is investigated. Displacements of binary droplets in a channel flow are compared by studying changes in the location of the leading and trailing edges for each droplet at different droplet spacing. Deformation and displacement of leading and tailing droplets with the ones for a single droplet are presented. The thesis concludes with application of the model to study displacement of a three-dimensional droplet. Dynamics of channel flow at the presence of water droplet was investigated considering the effects of Reynolds Number, Capillary number, Bond number, droplet size, and the contact angle. Displacement was characterized based on the changes of the droplet height and the contact wetted area.
Book Synopsis Surface Forces by : Nikolai V. Churaev
Download or read book Surface Forces written by Nikolai V. Churaev and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is devoted to long-range surface forces sig nificant far beyond a single monolayer and felt over tens or even hundreds of molecular layers adjacent to an interface. The transi tion from the concept of short-range effects that reigned earlier to the concept of long-range forces simultaneously signified the transition from a two-dimensional world to a three-dimensional one, incomparably richer in physicochemical phenomena. This transition took many years and evolved through many steps. It began with the Gouy-Chapman theory of diffuse ionic atmospheres, which together with London's theory of molecular forces was used as a basis for the development (beginning in 1937) of the DLVO theory of stability of lyophobic colloids. Further elaboration of the theory involved the introduction of new types of force, and a generalization (in 1954) to the case of interaction between unlike particles (hetero coagulation). This theory is fundamental in such large-scale prac tical problems as flotation, water treatment, dyeing, soil science, microbiology, and interaction between biological cells. This book is the first comprehensive monograph devoted to sur face forces. This fact makes it easier to attract the reader's interest; yet, the reader's demands become all the more difficult to satisfy completely. Indeed, the research that we review and analyze here covers about 50 years of work. Much data has been amassed, so that the main problem was a careful selection and an alysis.

Book Synopsis Droplet Interactions and Spray Processes by : Grazia Lamanna
Download or read book Droplet Interactions and Spray Processes written by Grazia Lamanna and published by Springer Nature. This book was released on 2020-03-14 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a selection of contributions to the DIPSI workshop 2019 (Droplet Impact Phenomena & Spray Investigations) as well as recent progress of the Int. Research Training Group “DROPIT”.The DIPSI workshop, which is now at its thirteenth edition, represents an important opportunity to share recent knowledge on droplets and sprays in a variety of research fields and industrial applications. The research training group “DROPIT” is focused on droplet interaction technologies where microscopic effects influence strongly macroscopic behavior. This requires the inclusion of interface kinetics and/or a detailed analysis of surface microstructures. Normally, complicated technical processes cover the underlying basic mechanisms, and therefore, progress in the overall process modelling can hardly be gained. Therefore, DROPIT focuses on the underlying basic processes. This is done by investigating different spatial and/or temporal scales of the problems and by linking them through a multi-scale approach. In addition, multi-physics are required to understand e.g. problems for droplet-wall interactions, where porous structures are involved.
Book Synopsis A study of droplet deformation by : Hannah Fry
Download or read book A study of droplet deformation written by Hannah Fry and published by Lulu.com. This book was released on 2012-09-14 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: In both engineering and medical applications it is often useful to use the knowledge of the conditions under which adhering liquid droplets appear, deform and interact with surrounding fluids, in order to either remove or create them. Examples include the de-wetting of aircraft surfaces and the process of injecting glue into the bloodstream in the treatment of aneurysms. In this study, we look at various methods of modelling a particular class of droplets - those attached to a wall in the presence of an external shear flow.
Book Synopsis Pattern Formations and Oscillatory Phenomena by : Hiroyuki Kitahata
Download or read book Pattern Formations and Oscillatory Phenomena written by Hiroyuki Kitahata and published by Elsevier Inc. Chapters. This book was released on 2013-05-09 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this chapter, we consider the motion of a droplet and the surrounding flow accompanied by the motion. Our specific attention is on the spontaneous and autonomous motion of a droplet. Such a system has no applied external force and no asymmetry imposed a priori. Nevertheless, the droplet moves by consuming energy and by breaking the symmetry of the system. The phenomenon reminds us of biological systems that can also move spontaneously. These systems, which are called self-propulsive systems, have recently been extensively studied after several model experiments were proposed using chemical reactions. The mechanism of such motion is less clear, though theoretical and computational studies have revealed several novel aspects of the motion in contrast with the motion under a given asymmetry. We discuss recently developed experimental systems. Then, we focus on a suspended droplet that swims, and explain how the result can be analyzed in terms of hydrodynamics by using the concept of surface tension. Finally, we apply the method to the analysis of a swimming suspended droplet induced propelled by a chemical pattern generated inside the droplet.

Book Synopsis Computational Methods in Multiphase Flow VIII by : P. Vorobieff
Download or read book Computational Methods in Multiphase Flow VIII written by P. Vorobieff and published by WIT Press. This book was released on 2015-04-20 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest research in one of the most challenging, yet most universally applicable areas of technology. Multiphase flows are found in all areas of technology, at all length scales and flow regimes, involving compressible or incompressible linear or nonlinear fluids. The range of related problems of interest is vast, including astrophysics, biology, geophysics, atmospheric process, and many areas of engineering. The solution of the equations that describe such complex problems often requires a combination of advanced computational and experimental methods. For example, any models developed must be validated through the application of expensive and difficult experimental techniques. Numerous problems in the area thus remain as yet unsolved, including modelling nonlinear fluids, modelling and tracking interfaces, dealing with multiple length scales, characterising phase structures, and treating drop break-up and coalescence. The papers contained in the book were presented at the eighth in a well established series of biennial conferences that began in 2001. They represent close interaction between numerical modellers and other researchers working to gradually resolve the many outstanding issues in understanding of multiphase flow. The papers in the book cover such topics as: Multiphase Flow Simulation; Bubble and Drop Dynamics; Interface Behaviour; Experimental Measurements; Energy Applications; Compressible Flows; Flow in Porous Media; Turbulent Flow; Image Processing; Heat Transfer; Atomization; Hydromagnetics; Plasma; Fluidised Beds; Cavitation.

Download or read book Flowing Matter written by Federico Toschi and published by Springer Nature. This book was released on 2019-09-25 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book, published in the Soft and Biological Matter series, presents an introduction to selected research topics in the broad field of flowing matter, including the dynamics of fluids with a complex internal structure -from nematic fluids to soft glasses- as well as active matter and turbulent phenomena. Flowing matter is a subject at the crossroads between physics, mathematics, chemistry, engineering, biology and earth sciences, and relies on a multidisciplinary approach to describe the emergence of the macroscopic behaviours in a system from the coordinated dynamics of its microscopic constituents. Depending on the microscopic interactions, an assembly of molecules or of mesoscopic particles can flow like a simple Newtonian fluid, deform elastically like a solid or behave in a complex manner. When the internal constituents are active, as for biological entities, one generally observes complex large-scale collective motions. Phenomenology is further complicated by the invariable tendency of fluids to display chaos at the large scales or when stirred strongly enough. This volume presents several research topics that address these phenomena encompassing the traditional micro-, meso-, and macro-scales descriptions, and contributes to our understanding of the fundamentals of flowing matter. This book is the legacy of the COST Action MP1305 “Flowing Matter”.

Book Synopsis The Physics of Microdroplets by : Jean Berthier
Download or read book The Physics of Microdroplets written by Jean Berthier and published by John Wiley & Sons. This book was released on 2012-04-30 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physics of Microdroplets gives the reader the theoretical and numerical tools to understand, explain, calculate, and predict the often nonintuitive observed behavior of droplets in microsystems. Microdrops and interfaces are now a common feature in most fluidic microsystems, from biology, to biotechnology, materials science, 3D-microelectronics, optofluidics, and mechatronics. On the other hand, the behavior of droplets and interfaces in today's microsystems is complicated and involves complex 3D geometrical considerations. From a numerical standpoint, the treatment of interfaces separating different immiscible phases is difficult. After a chapter dedicated to the general theory of wetting, this practical book successively details: The theory of 3D liquid interfaces The formulas for volume and surface of sessile and pancake droplets The behavior of sessile droplets The behavior of droplets between tapered plates and in wedges The behavior of droplets in microchannels The effect of capillarity with the analysis of capillary rise The onset of spontaneous capillary flow in open microfluidic systems The interaction between droplets, like engulfment The theory and application of electrowetting The state of the art for the approach of 3D-microelectronics using capillary alignment
