Book excerpt: This book is devoted to a fundamental understanding of the fluid dynamic nature of a bubble wake, more specifically the primary wake, in liquids and liquid-solid suspensions, an dto the role it plays in various important flow phenomena of multiphase systems. Examples of these phenomena are liquid/solids mixing, bubble coalescence and disintergration, particle entrainment to the freeboard, and bed contraction.

Available in PDF, EPUB and Kindle. Book excerpt: The time dependent motion of very small gas bubbles in liquids subjected to a linear pressure gradient has been studied. The problem is initiated by assuming that the motion of the bubbles through the liquid is governed by a linear drag law. In addition to the drag force, the apparent mass effect of the relative bubble motion and the effect of the bouyancy force have also been considered. It is found that the gas bubble slip [euqation follows : u [suscript g] - u [subscript l] / u [subscript l]] is a function of the liquid velocity gradient, the drag coefficient, and the mass densities of both liquid and gas. For air bubbles in water, the bubble slip asymptotically approaches zero for uniform flow, independent of initial bubble and liquid velocities, and approaches the value of 0.9967 for highly accelerating flows.

This book was released on 2013-03-09 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. Objective and Scope Bubbles, drops and rigid particles occur everywhere in life, from valuable industrial operations like gas-liquid contracting, fluidized beds and extraction to such vital natural processes as fermentation, evaporation, and sedimentation. As we become increasingly aware of their fundamental role in industrial and biological systems, we are driven to know more about these fascinating particles. It is no surprise, therefore, that their practical and theoretical implications have aroused great interest among the scientific community and have inspired a growing number of studies and publications. Over the past ten years advances in the field of small Reynolds numbers flows and their technological and biological applications have given rise to several definitive monographs and textbooks in the area. In addition, the past three decades have witnessed enormous progress in describing quantitatively the behaviour of these particles. However, to the best of our knowledge, there are still no available books that reflect such achievements in the areas of bubble and drop deformation, hydrodynamic interactions of deformable fluid particles at low and moderate Reynolds numbers and hydrodynamic interactions of particles in oscillatory flows. Indeed, only one more book is dedicated entirely to the behaviour of bubbles, drops and rigid particles ["Bubbles, Drops and Particles" by Clift et al. (1978)] and the authors state its limitations clearly in the preface: "We treat only phenomena in which particle-particle interactions are of negligible importance. Hence, direct application of the book is limited to single-particle systems of dilute suspensions.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Gas-Particle Flow is an edited, updated, and expanded version of a number of lectures presented on the “Gas-Solid Suspensions course organized by the von Karman Institute for Fluid Dynamics. Materials presented in this book are mostly analytical in nature, but some experimental techniques are included. The book focuses on relaxation processes, including the viscous drag of single particles, drag in gas-particles flow, gas-particle heat transfer, equilibrium, and frozen flow. It also discusses the dynamics of single particles, such as particles in an arbitrary flow, in a rotating gas, in a Prandtl-Meyer expansion, and in an oscillating flow. The remaining chapters of the book deal with the thermodynamics of gas-particle mixtures, steady flow through ducts, pressure waves, gas-particle jets, boundary layer, and momentum transfer. The experimental techniques included in this book present the powder feeders, the instrumentation on particle flow rate, velocity, concentration and temperature, and the measurement of the particle drag coefficient in a shock tube.

This book was released on 2012-12-06 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid flows that transfer heat and mass often involve drops and bubbles, particularly if there are changes of phase in the fluid in the formation or condensation of steam, for example. Such flows pose problems for the chemical and mechanical engineer significantly different from those posed by single-phase flows. This book reviews the current state of the field and will serve as a reference for researchers, engineers, teachers, and students concerned with transport phenomena. It begins with a review of the basics of fluid flow and a discussion of the shapes and sizes of fluid particles and the factors that determine these. The discussion then turns to flows at low Reynolds numbers, including effects due to phase changes or to large radial inertia. Flows at intermediate and high Reynolds numbers are treated from a numerical perspective, with reference to experimental results. The next chapter considers the effects of solid walls on fluid particles, treating both the statics and dynamics of the particle-wall interaction and the effects of phase changes at a solid wall. This is followed by a discussion of the formation and breakup of drops and bubbles, both with and without phase changes. The last two chapters discuss compound drops and bubbles, primarily in three-phase systems, and special topics, such as transport in an electric field.

Download or read book The Rise of Large Gas Bubbles Through Tubes Filled with Viscous Liquids written by Gary Leigh Brown and published by . This book was released on 1966 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of the velocity and the shape of large gas bubbles rising through tubes filled with viscous liquids is presented. Four tubes, with diameters ranging from 0. 446 inches to 3. 97 inches, and three liquids, with viscosities ranging from one to 200 centipoise, were used in the study. Data are correlated using the three dimensionless parameters characteristic of the system: the Reynolds number, the Froude number, and the Weber number. At high Reynolds numbers the Froude number was constant at a value of 0. 126, agreeing well with the theoretically predicted value of 0. 122 for a perfect fluid. At Reynolds numbers below 5000, the Froude number decreased sharply, with the Reynolds number of the flow and the surface tension of the liquid both affecting this decrease. The shape of the rising bubble was found to be independent of the tube diameter and of the physical properties of the liquid. The bubbles were all found to be spherical-capped.
