Scaling and Transition Effects on Hollow-Cylinder/Flare Shock/Boundary-Layer Interactions in Wind Tunnel Environments

What is it about?

This paper summarizes a collaborative effort to investigate differences observed between two nominally similar experiments conducted in two different Mach 5 wind tunnels. Supporting simulations and theory have been used to conduct a sensitivity analysis of various influences which show that disturbances in the wind tunnel flow play a primary role in scaling the flow phenomena. Experimental characterization of the respective wind tunnels demonstrates significant differences in the noise.
