TAILIEUCHUNG - DIRECT NUMERICAL SIMULATIONS OF GAS–LIQUID MULTIPHASE FLOWS

Gas–liquid multiphase flows play an essential role in the workings of Nature and the enterprises of mankind. Our everyday encounter with liquids is nearly always at a free surface, such as when drinking, washing, rinsing, and cooking. Similarly, such flows are in abundance in industrial applications: heat transfer by boiling is the preferred mode in both conventional and nuclear power plants, and bubbledriven circulation systems are used in metal processing operations such as steel making, ladle metallurgy, and the secondary refining of aluminum and copper. A significant fraction of the energy needs of mankind is met by burning liquid fuel, and a liquid must evaporate before it burns | Direct Numerical Simulations of Gas-Liquid Multiphase Flows Grétarĩìyggvason Ruben scardovelli and Stephane Zaleski Cambridge CAMBRIDi more information - DIRECT NUMERICAL SIMULATIONS OF GAS-LIQUID MULTIPHASE FLOWS Accurately predicting the behavior of multiphase flows is a problem of immense industrial and scientific interest. Using modern computers researchers can now study the dynamics in great detail and computer simulations are yielding unprecedented insight. This book provides a comprehensive introduction to direct numerical simulations of multiphase flows for researchers and graduate students. After a brief overview of the context and history the authors review the governing equations. A particular emphasis is placed on the one-fluid formulation where a single set of equations is used to describe the entire flow field and interface terms are included as singularity distributions. Several applications are discussed such as atomization droplet impact breakup and collision and bubbly flows showing how direct numerical simulations have helped researchers advance both our understanding and our ability to make predictions. The final chapter gives an overview of recent studies of flows with relatively complex physics such as mass transfer and chemical reactions solidification and boiling and includes extensive references to current work.
