Linear stability of hypersonic flow in thermochemical nonequilibrium

摘要

For flight at high Mach numbers, thermal and chemical nonequilibrium may exist in the mean flow and thus affect the stability of the flow. A computational tool was developed to analyze a hypersonic mean flow and its stability includihg thermochemical nonequilibrium. The mean flow analysis employs the Navier-Stokes equations with a translational/vibrational temperature model for thermal nonequilibrium and a five-species reacting air model for chemical nonequilibrium.
