Time Dependent, Compressible Simulations of Shear Flows: Tests of Outflow Boundary Conditions.

Abstract

Time dependent compressible numerical simulations of the onset of the Kelvin-Helmholtz instability in shear flows are described. The calculations performed use the Flux-Corrected Transport algorithm for solving the conservation equations for mass, momentum, energy on a two-dimensional grid. A method of implementing outflow boundary conditions is discussed and detailed benchmarks are given for two problems: a round jet flowing into a quiescent background gas and a diaphragm in a barrel. Finally, two calculations are described: one of a round jet surreounded by a slower co-flowing gas and the other of a splitter plate. (Author)
