ATOMIC RECOMBINATION IN NOZZLES. METHODS OF ANALYSIS FOR FLOWS WITH COMPLICATED CHEMISTRY

Abstract

The feasibility of performing accurate calculations on the non-equilibrium flow of a complicated gas mixture through nozzles, with particular reference to the propulsive nozzle of the hypersonic ram-jet is studied. Equations are given for the steady, quasi-one-dimensional, adiabatic flow of a gener l reacting gas mixture, consisting of N species related through N chemical reactions. A number of alternative methods of obtaining numerical solutions are evaluated. The formulation of the system of chemical reactions is also discussed, together with the availability of the large amount of thermo ynamic and chemical kinetic data which is required before a numeric l solution can be attempted. It is found that the most serious difficulty to be overcome before accurate non-equilibrium nozzle calculations can be performed, is obtaining reliable data on the rates of the many chemical reactions which may be involve .
