Numerous industrial systems or natural environments involvemultiphase flows with heat and mass transfer. The authors of thisbook present the physical modeling of these flows, in a unifiedway, which can include various physical aspects and several levelsof complexity.Thermal engineering and nuclear reactors; the extraction andtransport of petroleum products; diesel and rocket engines;chemical engineering reactors and fluidized beds; smoke or aerosoldispersion; landslides and avalanches & #8722; the modeling ofmultiphase flows with heat and mass transfer for all thesesituations can be developed following a common methodology. Thisbook is devoted to the description of the mathematical bases of howto incorporate adequate physical ingredients in agreement withknown experimental facts and how to make the model evolve accordingto the required complexity.ContentsPart 1.

His research activities cover fluid mechanics,combustion and flames, and multi-phase and granular flows. He was amember of the CNRS scientific committee and a laureate of theFrench Academy of Science.Fabien Anselmet is Professor at Ecole Centrale Marseille in France.His research activities focus on the turbulence of fluids and itsvaried applications in industry and in fields linked to theenvironment.With a unified, didactic style, this text presents tangible modelsof multiphase flows with heat and mass transfer with attention tovarious levels of complexities. It addresses thermal engineeringand nuclear reactors, extraction and transport of petroleumproducts, diesel engines and rocket engines, chemical engineeringreactors and fluidized beds, smoke or aerosol dispersion, andlandslides and avalanches. Engineers, researchers, and scientistswill appreciate the discussions of modeling principles, flows andgranular media, and fluctuations around averages.
