摘要

The research focused on the computational redesign of the shape of the bleed slot for the Purdue University Mach-6 wind tunnel to eliminate the axisymmetric separation bubble believed to exist on the inner surface of the bleed slot lip. This separation bubble is considered the most likely cause of the early transition of the boundary layers from laminar to turbulent conditions on the test section walls. This early transition, in turn, was deemed responsible for the high noise level in the tunnel at driver tube stagnation pressures above approximately 9 psia (61.8Pa) as of September 2004, and precluded the quiet operation of the tunnel at high Reynolds number (high stagnation pressure). A successful redesign of the shape of the bleed slot was achieved. No separation bubble was observed in detailed Navier-Stokes simulations at stagnation pressures up to 300 psia.
