Abstract
Ray Stalker’s invention of the free piston driver concept as uniquely suited to the study of high-enthalpy nonequilibrium phenomenon has resulted in a worldwide legacy of facilities such as the T1–T4 tunnels in Australia, HEG in Germany, T5 at Caltech, and HIEST at JAXA, Kakuda, Japan. In this talk, I will discuss recent and ongoing research in our group at Caltech that has focused on hypervelocity flows in which gas dynamics and thermochemistry are tightly coupled. To this end, we perform experiments in two impulse facilities which build on Ray Stalker’s legacy, including the T5 reflected shock tunnel and the Hypervelocity Expansion Tube facility.
