Nonequilibrium hypersonic flows over corners

Abstract

The hypersonic nonequilibrium flow of air over concave and convex corners is investigated. The description of the flowfield is based on the Euler equations and a chemical model that accounts for the finite rate reactions. An upwind formulation and the related space-marching technique are developed in order to achieve the numerical solution of the fluid dynamical and chemical equations, coupled together. The attention is focused on the effects of nonequilibrium chemistry on fluid dynamics.
