Effect of Particulates and Free Stream Disturbances on Hypervelocity Boundary Layer Transition
Abstract
The overall objective of this AFOSR YIP proposal is to investigate the effects of particulates and nose bluntness on hypersonic boundary layer transition at free stream Mach numbers of 6-10 at realistic flight enthalpy. The importance of the influence of these effects, especially particulates, on transition has long been acknowledged but has only begun to be simulated, and experimental measurements are exceedingly scarce. We will use a light gas gun ballistics range and a test tank with well-characterized free stream conditions to answer key questions about how particulates and nose bluntness affect the transition process using time-resolved imaging diagnostics. The imaging will primarily consist of time-resolved focusing schlieren imaging at acquisition rates up to 200 MHz.
