Abstract :
Summary form only given. We numerically investigate the effect of ionization on hypersonic flows by using an approximate Riemann fully three-dimensional MHD solver, WARP3, which includes multiple temperatures. The code calculates the ion fraction as a function of the electron temperature. We treat the flow as a single fluid with three (3) constituents, or namely ions, electrons and neutrals. It is believed that the inclusion of multi-temperature effects may explain the experimentally measured increase of shock stand-off distance encountered when an ionized hypersonic flow stagnates at a bluff body.
