THE CALCULATION OF EQUILIBRIUM GAS FLOWS,
Abstract
A new technique for computing the thermodynamic properties of gas mixtures is described which is necessary for calculating supersonic equilibrium gas flows over bodies. It is based on differential correlations obtained from the basic equations of gas dynamics and equations of chemical equilibrium. This approach was used for calculating supersonic equilibrium gas flows past blunt bodies by the method of integral relations developed by A. A. Dorodnitsyn and O. M. Belotserkovsky. One of the advantages of this technique consists in that the obtained system of differential equations is associated with the initial approximate system of the numerical scheme for solving the gas dynamic problem and integrated together with the latter by the same method. This procedure requires less computer time than the iteration method. Supersonic flows of air over a sphere were calculated in the range of M = 4 to 30, rho = 0.01 atm, T = 300K as an illustrative example. A comparison of the results with those obtained by the iteration method shows satisfactory agreement. (Author)
