Abstract:

This Final Report describes our program in studies of laminarturbulent stability and transition in non-equilibrium chemistry flows characteristic of those on the forebodies of hypersonic vehicles. The configuration best modelling a hypersonic vehicle is an elliptic cone. Specifically, we investigated and optimized a Parabolized Navier-Stokes solution for the basic-state flow past a sharp elliptic cone including the region between the wall and the shock. We formulated the Parabolized Stability Equations for 3-D flows.
