Study of unsteady shock motion in shock/turbulence interaction

The interaction of turbulence with a shock wave is common in high speed flow appli- cations. The shock wave distorts upon interaction and an unsteadiness is observed in the flow. The amount of distortion depends on the intensity of the incoming fluctuations and at very high intensities, the shock wave cannot maintain its profile and instead develops holes. This rather interesting feature has been observed in direct numerical simulations (DNS) of shock-turbulence interaction.
