Numerous industrial systems or natural environments involve
multiphase flows with heat and mass transfer. The authors of this
book present the physical modeling of these flows, in a unified
way, which can include various physical aspects and several levels
of complexity.
Thermal engineering and nuclear reactors; the extraction and
transport of petroleum products; diesel and rocket engines;
chemical engineering reactors and fluidized beds; smoke or aerosol
dispersion; landslides and avalanches & #8722; the modeling of
multiphase flows with heat and mass transfer for all these
situations can be developed following a common methodology. This
book is devoted to the description of the mathematical bases of how
to incorporate adequate physical ingredients in agreement with
known experimental facts and how to make the model evolve according
to the required complexity.

About the Authors
Roland Borghi is Professor Emeritus at Ecole Centrale Marseille
in France and works as a consultant in the space, petrol and
automobile sectors. His research activities cover fluid mechanics,
combustion and flames, and multi-phase and granular flows. He was a
member of the CNRS scientific committee and a laureate of the
French Academy of Science.
Fabien Anselmet is Professor at Ecole Centrale Marseille in France.
His research activities focus on the turbulence of fluids and its
varied applications in industry and in fields linked to the
environment.
With a unified, didactic style, this text presents tangible models
of multiphase flows with heat and mass transfer with attention to
various levels of complexities. It addresses thermal engineering
and nuclear reactors, extraction and transport of petroleum
products, diesel engines and rocket engines, chemical engineering
reactors and fluidized beds, smoke or aerosol dispersion, and
landslides and avalanches. Engineers, researchers, and scientists
will appreciate the discussions of modeling principles, flows and
granular media, and fluctuations around averages.
