Some Advances in Research of Shock Wave Turbulent Boundary Layer Interactions

Abstract

A critical analysis of some recent experimental and computational research of 2-D and 3-D shock wave/turbulent boundary layer interaction (SWTBLI) is carried out. The specific stages of turbulent boundary layer separation development in a vicinity of compression ramps, forward- and backward- facing steps, one- and double-fin configurations are considered. The flowfield topology and principal physical processes are analyzed and specified for different cases of SWTBLI. The examples of modern numerical modeling on a basis of the Reynolds-averaged Navier-Stokes equations with various turbulence models as well as Direct Numerical Simulation (DNS) and Large Eddy Simulation (LES) are demonstrated and compared. The perspectives and problems of future SWTBLI studies are discussed.
