The joint application of direct numerical simulation (DNS) and a combined multiple-direct forcing and immersed boundary method (MDF/IBM) is proposed to investigate the transitional boundary-layer flow induced by three-dimensional roughness elements. The multi-direct forcing technique is used to calc

The three-dimensional inviscid-viscous interaction generated by the intersection of an oblique shock with a turbulent boundary layer is examined theoretically. An incoming Mach 4 equilibrium turbulent boundary layer at Reynolds number Re~ = 2 ร 105 interacts with an oblique shock formed by a 16 ยฐ sh
