“…In Fig. 4, the calculated pitot pressure profiles at four different streamwise locations within the inlet are compared with a PEPSI-S (NASA Lewis PNS code) analysis 18 and experimental data. The present analysis shows excellent agreement with the experimental data and slightly better agreement than the PEPSI-S analysis, especially at the far downstream flow station (47 in.…”

An implicit pressure correction algorithm developed to solve the Navier-Stokes equations for high-speed flows ranging up to the hypersonic flow regime is described. A multistep pressure correction procedure with an implicit density treatment is used to establish the pressure and velocity fields. A smart numerical dissipation scheme adapting monotonically at extrema is developed to capture strong shocks. Numerical solutions for inlet and reattaching free-shear layer flows are compared with experimental data and other numerical results.

“…In such hypersonic flows, the temperature is very large, and the air flow, which is a mixture of monoatomic and polyatomic gases, is modified by chemical reactions. The characteristics of the mixture (viscosity and specific heats) then depend on its temperature (see [25]). One way to take into account this variability is to use appropriate constitutive laws for the air.…”

High temperature gases, for instance in hypersonic reentry flows, show complex phenomena like excitation of rotational and vibrational energy modes, and even chemical reactions. For flows in the continuous regime, simulation codes use analytic or tabulated constitutive laws for pressure and temperature. In this paper, we propose a BGK model which is consistent with any arbitrary constitutive laws, and which is designed to make high temperature gas flow simulations in the rarefied regime. A Chapman-Enskog analysis gives the corresponding transport coefficients. Our approach is illustrated by a numerical comparison with a compressible Navier-Stokes solver with rotational and vibrational non equilibrium. The BGK approach gives a deterministic solver with a computational cost which is close to that of a simple monoatomic gas.
