Produktbeschreibung

This single-volume work gives an introduction to the fields of transition, turbulence, and combustion modeling of compressible flows and provides the physical background for today's modeling approaches in these fields. It presents basic equations and discusses fundamental aspects of hydrodynamical instability.
