Summary: Containing contributions from leading academic and industrial researchers, this book provides a much needed update of foam science research. The first section of the book presents an accessible summary of the theory and fundamentals of foams. This includes chapters on morphology, drainage, Ostwald ripening, coalescence, rheology, and pneumatic foams. The second section demonstrates how this theory is used in a wide range of industrial applications, including foam fractionation, froth flotation and foam mitigation. It includes chapters on suprafroths, flotation of oil sands, foams in enhancing petroleum recovery, Gas-liquid Mass Transfer in foam, foams in glass manufacturing, fire-fighting foam technology and consumer product foams. Key features: Foam fractionation is an exciting and emerging technology, starting to gain significant attention Discusses a vital topic for many industries, especially mineral processing, petroleum engineering, bioengineering, consumer products and food sector Links foam science theory to industrial applications, making it accessible to an engineering science audience Summarizes the latest developments in this rapidly progressing area of research Contains contributions from leading international researchers from academia and industry.Summary: Intro -- Foam Engineering: Fundamentals and Applications -- Contents -- About the Editor -- List of Contributors -- Preface -- 1 Introduction -- 1.1 Gas-Liquid Foam in Products and Processes -- 1.2 Content of This Volume -- 1.3 A Personal View of Collaboration in Foam Research -- Part I Fundamentals -- 2 Foam Morphology -- 2.1 Introduction -- 2.2 Basic Rules of Foam Morphology -- 2.2.1 Foams, Wet and Dry -- 2.2.2 The Dry Limit -- 2.2.3 The Wet Limit -- 2.2.4 Between the Two Limits -- 2.3 Two-dimensional Foams -- 2.3.1 The Dry Limit in 2D -- 2.3.2 The Wet Limit in 2D -- 2.3.3 Between the Two Limits in 2D -- 2.4 Ordered Foams -- 2.4.1 Two Dimensions -- 2.4.2 Three Dimensions -- 2.5 Disordered Foams -- 2.6 Statistics of 3D Foams -- 2.7 Structures in Transition: Instabilities and Topological Changes -- 2.8 Other Types of Foams -- 2.8.1 Emulsions -- 2.8.2 Biological Cells -- 2.8.3 Solid Foams -- 2.9 Conclusions -- Acknowledgements -- References -- 3 Foam Drainage -- 3.1 Introduction -- 3.2 Geometric Considerations -- 3.3 A Drained Foam -- 3.4 The Continuity Equation -- 3.5 Interstitial Flow -- 3.6 Forced Drainage -- 3.7 Rigid Interfaces and Neglecting Nodes: The Original Foam Drainage Equation -- 3.8 Mobile Interfaces and Neglecting Nodes -- 3.9 Neglecting Channels: The Node-dominated Model -- 3.10 The Network Model: Combining Nodes and Channels -- 3.11 The Carman - Kozeny Approach -- 3.12 Interpreting Forced Drainage Experiments: A Detailed Look -- 3.13 Unresolved Issues -- 3.14 A Brief History of Foam Drainage -- References -- 4 Foam Ripening -- 4.1 Introduction -- 4.2 The Very Wet Limit -- 4.3 The Very Dry Limit -- 4.3.1 Inter-bubble Gas Diffusion through Thin Films -- 4.3.2 von Neumann Ripening for 2D Foams -- 4.3.3 3D Coarsening -- 4.4 Wet Foams -- 4.5 Controlling the Coarsening Rate -- 4.5.1 Gas Solubility -- 4.5.2 Resistance to Gas Permeation.PPN: PPN: 809715244Package identifier: Produktsigel: ZDB-26-MYL | ZDB-30-PAD | ZDB-30-PAD | ZDB-30-PQE
