Session MN - Compressible Flows.
MIXED session, Tuesday afternoon, November 23
Orcas, Westin Seattle
Direct numerical simulations of two canonical configurations, a 24-degree compression ramp and shock impinging a wall with reflection, are performed to study shockwave and turbulent boundary layer interactions. The Mach number of the incoming boundary layers is 2.9 and the Reynolds number is 2400 based on the momentum thickness. An assessment of the size and resolution of the computational domains are given. An analysis of the simulation data are presented. The shock unsteadiness, turbulence amplification, and changes of length scales through the shockwave and turbulent boundary layer interaction are studied.
