CALCULATION OF A 3-DIMENSIONAL SHOCK WAVE-TURBULENT BOUNDARY-LAYER INTERACTION

This paper deals with the numerical simulation of a shock wave-turbulent boundary-layer interaction in a three-dimensional channel by solution of the Reynolds averaged Navier-Stokes equations with a mixing-length turbulence model. The numerical method is characterized by an explicit centered finite-difference scheme associated with a multigrid convergence acceleration. The computed configuration is well suited to the validation of a three-dimensional Navier-Stokes solver since the flow has a very complex three-dimensional structure, although the channel geometry is simple. Comparison with experiment shows that the numerical results obtained in a mesh containing about 600,000 points are satisfactory. © 1990 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
