Hypersonic flow in chemical non-equilibrium: A comparison of thin-layer Navier-Stokes and coupled Euler/boundary layer computations (Q1327274)

A comparison of the computed flowfields for viscous hypersonic flow in chemical non-equilibrium is presented. Two different approximations of the aerothermochemistry equations have been considered: the thin-layer Navier-Stokes equations and a second-order coupling of the Euler and boundary layer equations. The detailed agreement obtained in the computed solutions for hypersonic flow over a hyperboloid provides a verification of the accuracy of the numerical methods employed.
