The interaction of three-dimensional isotropic turbulence with a plane shock at Mach numbers of M = 2.0 and M = 3.0 is investigated via direct numerical simulation. The numerical scheme is based on a characteristic-type formulation of the Navier-Stokes equations and uses fifth-order upwind schemes in space, a fourth order Runge Kutta scheme in time and a shock-fitting as inlet condition. The isotropic turbulence was generated in a separate computation based on a prescribed energy spectrum. This turbulent flow is considered as frozen, and is convected through the shock with a prescribed average shock speed. An FFT interpolation is used to obtain the upstream values at the instantaneous shock location.
