Abstract : In this final report covering the period 1993-1994, the preliminary results of the research on direct numerical simulation of compressible turbulent flows are presented. Specifically, the adaptive Legendre polynomial spectral element method with the mixed explicit-implicit(MEI) Taylor-Galericin formulation is used in order to capture detailed physics involved in three-dimensional shock wave turbulent boundary layer interactions.
