Experimental investigation of interactions between turbulent cylinder wake and spherical shock wave

Abstract: Interactions between a spherical shock wave and a turbulent cylinder wake are studied with wind tunnel experiments. The shock wave is generated outside the wake and propagates across the turbulent wake. Instantaneous streamwise velocity is measured on the wake centerline while peak overpressure of the shock wave is measured outside the wake after the shock wave has passed across the wake. The experiments are performed for various conditions of the cylinder wake to investigate the influences of the root-mean-sq… Show more

“…The influence of compressibility on vorticity fluctuation after the interaction was also examined. In attempting to evaluate the turbulent parameters across the interaction, the interaction of turbulent cylindrical wake and spherical shock wave was investigated experimentally by Aruga et al (2020). The effects on the integral length scale of freestream turbulence on junction flow behavior have been demonstrated and the data of such a kind of study show the dependency of shock strength on the amplification of the turbulence (Lange and Lynch, 2020).…”
