A Study on the Separation Length of Shock Wave/Turbulent Boundary Layer Interaction

A Study on the Separation Length of Shock Wave/Turbulent Boundary Layer Interaction

The separation length of shock wave/boundary layer interaction (SWBLI) was studied by a numerical method, which was validated by experimental results. The computational domain was two-dimensional (2-D). The flow field was an incident oblique shock interacting with a turbulent boundary layer on a fla...
