This book is devoted to the numerical analysis of compressible fluids in
the spirit of the celebrated Lax equivalence theorem. The text is aimed
at graduate students in mathematics and fluid dynamics, researchers in
applied mathematics, numerical analysis and scientific computing, and
engineers and physicists.
The book contains original theoretical material based on a new approach
to generalized solutions (dissipative or measure-valued solutions). The
concept of a weak-strong uniqueness principle in the class of
generalized solutions is used to prove the convergence of various
numerical methods. The problem of oscillatory solutions is solved by an
original adaptation of the method of K-convergence. An effective method
of computing the Young measures is presented. Theoretical results are
illustrated by a series of numerical experiments.
Applications of these concepts are to be expected in other problems of
fluid mechanics and related fields.
