Large eddy simulation of compressible channel flow

A large eddy simulation method for compressible channel flow simulations is developed and validated. The method separates the resolvable scale motions from the unresolvable (subgrid) scales by applying a spatial filter to the compressible Navier-Stokes equations. The Leonard and cross terms which appear due to the filtering procedure are modeled based on a Taylor series expansion. The subgrid scale Reynolds terms are modeled using a compressible extension of an existing incompressible model for wall bounded flows. The equations are solved numerically using a modified four-step Runge-Kutta procedure in time and second or fourth-order differences in space.
