A FORTRAN COMPUTER CODE FOR INVISCID, NONEQUILIBRIUM STREAMTUBE FLOW

Abstract

A Fortran IV computer program for calculating nonequilibrium streamtube flows has been developed. Inviscid gas properties can be obtained for quasi-one-dimensional flows following varying conditions of pressure, density, velocity, or cross-sectional area arbitrarily specified in the streamwise direction. In this program, the kinetic model can include up to 20 species and 40 reversible chemical reactions. The numerical integration method has a mathematical accuracy check to determine step size. This eliminates the need for repeated trial runs for optimization. Controlled injection of small perturbations is employed to run the program with some chemical reactions near- equilibrium.
