Book excerpt: This thesis is comprised of three parts, focusing on the dynamics of miscible liquid interfaces, the dynamics of ultra-low surface tension liquid interfaces, and the spreading of "rinsing" liquids across rotating, horizontal substrates. Miscible liquids commonly contact one another in natural and technological situations, often as one liquid suspended within another or in the proximity of a solid substrate. A systematic experimental study of the shape evolution of pendant and sessile droplets immersed in miscible environments was conducted. We present experimental findings that have distinctly different shape evolution and time-dependent dynamics from droplets present in immiscible environments, which have been reported previously. A complementary numerical approach to compute the concentration and velocity fields of these systems using a simplified set of governing equations is paired with our experimental findings. Additionally, a study of droplets freely rising through a miscible, more viscous liquid was conducted. We report observations of droplets of water rising through glycerol and corn syrup. A class of ultra-low surface tension liquids are aqueous two-phase solutions, which form by the phase separation of different polymers within an aqueous solution when a critical threshold in concentration of polymer is exceeded. We investigate two configurations of water-water emulsions: a sessile drop, and a drop at a planar liquid-liquid interface of an aqueous two-phase solution. A particular class of liquids that spread across solid surfaces are "rinsing" liquids. When applied to a rotating substrate, the dynamics of rinsing liquids are interesting fundamentally in the interaction of several classic modes of spreading and industrially in a variety of cleaning applications, such as in the manufacturing of silicon wafers. An investigation of the spreading of a rinsing liquid across a horizontal, rotating hydrophilic substrate was conducted. We present experimental findings of the spreading radius of the rinsing liquid, in which we observed four distinct growth rates across the parameter space and use lubrication theory to explain the phenomena.

Book Synopsis Transport Processes at Fluidic Interfaces by : Dieter Bothe
Download or read book Transport Processes at Fluidic Interfaces written by Dieter Bothe and published by Birkhäuser. This book was released on 2017-07-13 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several physico-chemical processes that determine the behavior of multiphase fluid systems – e.g., the fluid dynamics in the different phases and the dynamics of the interface(s), mass transport between the fluids, adsorption effects at the interface, and transport of surfactants on the interface – and result in heterogeneous interface properties. In general, these processes are strongly coupled and local properties of the interface play a crucial role. A thorough understanding of the behavior of such complex flow problems must be based on physically sound mathematical models, which especially account for the local processes at the interface. This book presents recent findings on the rigorous derivation and mathematical analysis of such models and on the development of numerical methods for direct numerical simulations. Validation results are based on specifically designed experiments using high-resolution experimental techniques. A special feature of this book is its focus on an interdisciplinary research approach combining Applied Analysis, Numerical Mathematics, Interface Physics and Chemistry, as well as relevant research areas in the Engineering Sciences. The contributions originated from the joint interdisciplinary research projects in the DFG Priority Programme SPP 1506 “Transport Processes at Fluidic Interfaces.”
Book Synopsis Fundamentals of Two-Fluid Dynamics by : Daniel D. Joseph
Download or read book Fundamentals of Two-Fluid Dynamics written by Daniel D. Joseph and published by Springer. This book was released on 1992-12-18 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-fluid dynamics is a challenging subject rich in physics and prac tical applications. Many of the most interesting problems are tied to the loss of stability which is realized in preferential positioning and shaping of the interface, so that interfacial stability is a major player in this drama. Typically, solutions of equations governing the dynamics of two fluids are not uniquely determined by the boundary data and different configurations of flow are compatible with the same data. This is one reason why stability studies are important; we need to know which of the possible solutions are stable to predict what might be observed. When we started our studies in the early 1980's, it was not at all evident that stability theory could actu ally work in the hostile environment of pervasive nonuniqueness. We were pleasantly surprised, even astounded, by the extent to which it does work. There are many simple solutions, called basic flows, which are never stable, but we may always compute growth rates and determine the wavelength and frequency of the unstable mode which grows the fastest. This proce dure appears to work well even in deeply nonlinear regimes where linear theory is not strictly valid, just as Lord Rayleigh showed long ago in his calculation of the size of drops resulting from capillary-induced pinch-off of an inviscid jet.

Book Synopsis Fluid Interfaces by : Eduardo Guzmán
Download or read book Fluid Interfaces written by Eduardo Guzmán and published by MDPI. This book was released on 2021-03-02 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid interfaces are promising candidates for confining different types of materials, e.g., polymers, surfactants, colloids, and even small molecules, to be used in designing new functional materials with reduced dimensionality. The development of such materials requires a deepening of the physicochemical bases underlying the formation of layers at fluid interfaces as well as on the characterization of their structures and properties. This is of particular importance because the constraints associated with the assembly of materials at the interface lead to the emergence of equilibrium and features of dynamics in the interfacial systems, which are far removed from those conventionally found in traditional materials. This Special Issue is devoted to studies on the fundamental and applied aspects of fluid interfaces, and attempts to provide a comprehensive perspective on the current status of the research field.
Book Synopsis Vapor-Liquid Interfaces, Bubbles and Droplets by : Shigeo Fujikawa
Download or read book Vapor-Liquid Interfaces, Bubbles and Droplets written by Shigeo Fujikawa and published by Springer. This book was released on 2011-04-20 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physically correct boundary conditions on vapor-liquid interfaces are essential in order to make an analysis of flows of a liquid including bubbles or of a gas including droplets. Suitable boundary conditions do not exist at the present time. This book is concerned with the kinetic boundary condition for both the plane and curved vapor-liquid interfaces, and the fluid dynamics boundary condition for Navier-Stokes(fluid dynamics) equations. The kinetic boundary condition is formulated on the basis of molecular dynamics simulations and the fluid dynamics boundary condition is derived by a perturbation analysis of Gaussian-BGK Boltzmann equation applicable to polyatomic gases. The fluid dynamics boundary condition is applied to actual flow problems of bubbles in a liquid and droplets in a gas.

Book Synopsis Geometry and Dynamics of Fluid-fluid Interfaces by : Matthew Evan Thrasher
Download or read book Geometry and Dynamics of Fluid-fluid Interfaces written by Matthew Evan Thrasher and published by . This book was released on 2007 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: We observed the evolution of unstable fluid interfaces in experiments on viscous fingering, pinch-off, and bouncing jets. If we can first identify classes of universal behavior, then we can begin building a unified framework to understand nonlinear processes. We performed the first experimental test of the harmonic moments of viscous fingering patterns, grown by injecting air into a thin layer of silicone oil, which was confined between two closely spaced plates, called a Hele-Shaw cell. We observed that the predicted decay of the moments was accurate within our measurement uncertainty, which confirmed the predicted conservation of the moments for zero surface tension. With greater forcing, the air bubble will undergo a secondary tip-splitting instability, where the fingers of air fork into two or more fingers. We discovered two selection rules for the changing base width and the nearly invariant opening angle of fjords, which are the regions of oil between the fingers of air. We then compared our experiments on viscous fingering with diffusion-limited aggregation (DLA), a model of un-stable growth. We calculated that DLA and viscous fingering have the same spectrum of singularities [called f([alpha])] within measurement uncertainty. Since the spectrum is a global encapsulation of the growth dynamics and scaling properties, we say that the two processes are in the same scaling universality class. All of these results for viscous fingering are expected to apply to other physical systems which approximate Laplacian growth, a model of an interface where its growth rate is determined by the local gradient of a field [phi] obeying Laplace's equation [gradient2 phi] = 0. Next we present preliminary work on the experimental test of two predictions for flows in Hele-Shaw cells: 1) soliton-like behavior of two viscous domains and 2) self-similar, universal pinch-off of an inviscid bubble in a viscous liquid. Finally, we report our observations and analysis of a liquid stream with constant viscosity (i.e. Newtonian) which rebounds from the free surface of a moving bath. The stream bounces on a thin layer of lubricating air which is replenished by the relative motion of the jet and the bath.
