Numerical Methods for Unsteady Compressible Flow Problems (eBook, ePUB)

• Format: ePub

Produktbeschreibung

This book is written to give both mathematicians and engineers an overview of the state of the art in the field, as well as of new developments. The focus is on methods for the compressible Navier-Stokes equations, the solutions of which can exhibit shocks, boundary layers and turbulence.
