Student Training Program in Rayleigh Imaging of Mach 8 Boundary Layer Flow Around an Elliptic Cone Body

摘要

Since the original parent grant expired two years ago, the work has been done in close association with our on-going program on Microwave-Driven Air Plasma Studies for Drag Reduction and Power Extraction in Supersonic Air (AFOSR Grant Number F49620-00-1-0034), as well as research aspects associated with the 'Radiatively-Driven, Hypersonic Wind Tunnel' effort. The MHz-rate imaging on an elliptic cone body at Mach 8 reached completion this year with the graduation of Mark Huntley, a student supported by the AASERT program, and Pingfan Wu, a student associated with that effort but supported with other funds because of his non-citizenship. Brendan McAndrew and Robert Murray developed a microwave- coupled Mach 3 wind tunnel under AASERT program support, and they are using that facility to study air plasmas in high-speed flow. Vincent Chiravalle is expanding the plasma concept to examine potential for building compact, high specific, impulse thrusters as part of the plasma effort. Robert Anderson, who finished his Ph.D. this past summer, developed modeling for the Radiatively- Driven, Hypersonic Wind Tunnel effort, and Kumar Raman, who recently completed his Masters' Degree, made measurements of boundary layer growth and heat transfer in high Reynolds' number, real-gas, supersonic flow.
