Abstract. Our interest in the stability analysis of the high-order continuum (HOC) equations is motivated by the relevance to the development of a hybrid method combining such equations with the Direct Simulation Monte-Carlo (DSMC) technique for the computation of hypersonic flows in all regimes – continuum, transition, and rarefied. The hybrid approach allows the effects of thermophysics (ther...

As the first part of an ongoing study on heat flux and abation on hypersonic vehicles, a material response implicit solver with solid ablation and pyrolysis is developed. As a first step, code-to-code validations and comparisons with experimental data are performed. A study of the various effects of pyrolysis gas within an ablator is also performed; using realistic re-entry conditions on a gene...

Weakly ionized plasmas, formed in high enthalpy hypersonic flows, can be actively manipulated via imposed magnetic fields—a concept termed magnetohydrodynamic (MHD) flow control. Imposed MHD effects, within flows that exhibit multiple shock interactions, are consequential for emerging aerospace technologies, including the possibility of replacing mechanical control surfaces with actuation. Howe...

Shock waves generated at different parts of vehicle interact with the boundary layer over the surface at high Mach flows. The adverse pressure gradient across strong shock wave causes the flow to separate and peak loads are generated at separation and reattachment points. The size of separation bubble in the shock boundary layer interaction flows depends on various parameters. Reynolds-averaged...
