Chemical and vibrational nonequilibrium flow in a hypersonic axisymmetric nozzle

摘要

Chemical and vibrational nonequilibrium flow in a hypersonic axisymmetric nozzle. The aim of this work is to analyse the high temperature flow in a hypersonic nozzle taking into account the chemical and vibrational nonequilibrium for the different species of air mixture. The transition from 3D to 2D axisymmetric is assured by the technique of the domain pertubation. The numerical results show the difference between two different models: the model of 3 chemical reactions (Zeldovich model) and the model of 17 chemical reactions.
