The goal of this is book to give a detailed presentation of
multicomponent flow models and to investigate the mathematical structure
and properties of the resulting system of partial differential
equations. These developments are also illustrated by simulating
numerically a typical laminar flame. Our aim in the chapters is to treat
the general situation of multicomponent flows, taking into account
complex chemistry and detailed transport phe- nomena. In this book, we
have adopted an interdisciplinary approach that en- compasses a
physical, mathematical, and numerical point of view. In par- ticular,
the links between molecular models, macroscopic models, mathe- matical
structure, and mathematical properties are emphasized. We also often
mention flame models since combustion is an excellent prototype of
multicomponent flow. This book still does not pretend to be a complete
survey of existing models and related mathematical results. In
particular, many subjects like multi phase-flows, turbulence modeling,
specific applications, porous me- dia, biological models, or
magneto-hydrodynamics are not covered. We rather emphasize the
fundamental modeling of multicomponent gaseous flows and the qualitative
properties of the resulting systems of partial dif- ferential equations.
Part of this book was taught at the post-graduate level at the Uni-
versity of Paris, the University of Versailles, and at Ecole Poly
technique in 1998-1999 to students of applied mathematics.
