In the present study, a direct numerical simulation (DNS) of a shock boundary layer interaction injected with a freestream flow of M = 2.9 over a 24 degree compression ramp is performed to investigate the increases in the pressure fluctuation. The rapid rise in the pressure at the primary shock location is inherent due to the shock compression. However, the increase in the pressure fluctuation is a complex process in which the augmented turbulence plays a dominant role due to the second phase flow deflection. With the lack of understanding at present, the DNS study is an attempt to reveal its pressure amplification mechanism.
