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.”

Gas / liquid contact apparatuses are widely used in chemical, biochemical or pharmaceutical industry to provide and transfer gas species as reactant from the gaseous phase to pre-dissolved reactants in the liquid phase enabling a preferred reaction. The global and local transport are complex interlinked processes and therefore in practice in reactor design industry, mostly empirically correlated. For a secure control of the overall process and a more efficient reactor design, the local transport processes at gas / liquid interfaces need to be investigated in complexity reduced systems to be understood. Elongated bubbles, Taylor bubbles, in vertical channels 5.5 < D < 8 mm overcome the problem of dynamic shape deformation, complex 3D rise trajectories and they have a volume independent rise velocity, which make them the ideal experiment for reliable and reproducible investigations. Detailed optical measurements of global and local processes via high-speed Shadowgraphy, 2D2C PIV and p-2D LIF give new insights into the dependency of local bubble shape and global terminal rise velocity, establish a Sherwood correlation of shrinking CO2 bubbles in various channel sizes and shows the coupling of local transport phenomena at the bubble interface and the mixing in the wake region.

Besides their intrinsic mathematical interest, geometric partial differential equations (PDEs) are ubiquitous in many scientific, engineering and industrial applications. They represent an intellectual challenge and have received a great deal of attention recently. The purpose of this volume is to provide a missing reference consisting of self-contained and comprehensive presentations. It includes basic ideas, analysis and applications of state-of-the-art fundamental algorithms for the approximation of geometric PDEs together with their impacts in a variety of fields within mathematics, science, and engineering. - About every aspect of computational geometric PDEs is discussed in this and a companion volume. Topics in this volume include stationary and time-dependent surface PDEs for geometric flows, large deformations of nonlinearly geometric plates and rods, level set and phase field methods and applications, free boundary problems, discrete Riemannian calculus and morphing, fully nonlinear PDEs including Monge-Ampere equations, and PDE constrained optimization - Each chapter is a complete essay at the research level but accessible to junior researchers and students. The intent is to provide a comprehensive description of algorithms and their analysis for a specific geometric PDE class, starting from basic concepts and concluding with interesting applications. Each chapter is thus useful as an introduction to a research area as well as a teaching resource, and provides numerous pointers to the literature for further reading - The authors of each chapter are world leaders in their field of expertise and skillful writers. This book is thus meant to provide an invaluable, readable and enjoyable account of computational geometric PDEs
