Direct Numerical Simulation of a Reflected-Shock- Wave/Turbulent-Boundary-Layer Interaction

Cf = skin-friction coefficient f = frequency fs = frequency of shock motion J = Jacobian matrix of the grid transformation Lsep = separation length M = freestream Mach number p = pressure Re = Reynolds number based on Re = Reynolds number based on Re = Reynolds number based on Sij = rate-of-strain tensor SL = dimensionless frequency of shock motion based on Lsep and U1 T = temperature u = velocity in the streamwise direction v = velocity in the spanwise direction w = velocity in the wall-normal direction x = coordinate in the streamwise direction y = coordinate in the spanwise direction z = coordinate in the wall-normal direction = 99% thickness of the incoming boundary layer = displacement thickness of the incoming boundary layer = momentum thickness of the incoming boundary layer = density h i = averaged quantity
