A Fundamental Study of Hypersonic Unstarts

Abstract

Activities for the first year were primarily focused on laying the groundwork for accomplishing the ultimate goals of this investigation. Required hardware and software was obtained and implemented. Grid generators were tested and one was selected, as was the primary computational tool. Activities in the second year were directed towards beginning the three dimensional Euler, then Navier-Stokes calculations, to establish a steady-state time accurate baseline, which could then be perturbed to study the influence of downstream disturbances. Both Euler and laminar Navier-Stokes solutions were calculated. Hypersonic, Inlet, Unstart.
