Abstract
The coherent structure in two-dimensional mixing layers is simulated n umerically with the compressible Navier-Stokes equations. The Navier-S tokes equations are discretized with high-order accurate upwind compac t schemes. The process of development of flow structure is presented: loss of stability, development of Kelvin-Helmholtz instability, rollin g up and pairing. The time and space development of the plane mixing l ayer and influence of the compressibility are investigated.
