Passive and Active Patterned Roughness for Cross-flow Transition Control at Mach 6
Abstract
Conduct extensive experimental studies on a cone model equipped with a motorized 3-D traversing mechanism at US AF Academy s Ludwieg tube facility to, 1) Demonstrate the receptivity of stationary cross-flow modes to the passive and active (plasma) patterned roughness in a 3-D boundary layer at Mach 6; 2) Utilize this receptivity to demonstrate the degree to which transition to turbulence can be delayed by the passive and active (plasma) patterned roughness at Mach 6; 3) Determine the effect of initial conditions (turbulence and acoustic levels) on the transition location and control through a direct comparison between the previous experiments with the same model in the NASA Mach 3.5 quiet condition, and the AF Academy Ludwieg Tube flow condition.
