The computation of hypersonic ionized flows in chemical and thermal nonequlibrium
Abstract
A numerical method to compute a twodimensional hypersonic flowfield that is ionized and in thermochemical nonequilibrium has been developed. Such a flowfield is described by coupled timedependent partial differential equations for the conservation of species mass, massaverage momentum, vibrational energy of each diatomic species, electron energy, and total massaveraged energy. The steadystate solution to these fully coupled equations is obtained using an implicit GaussSeidel line relaxation technique. The computed electron densities in the flowfield compare well with experimental results.
