UNIDIMENSIONAL THEORY OF SUPERSONIC COMBUSTION,

Abstract

This paper outlines a generalized unidimensional theory of supersonic combustion. It considers a stream of oxidizer flowing along a tube with lateral fuel supply governed by a certain injection law and the combustion occurring in conditions in which the pressure is kept constant. The principal results obtained by using the simple model under consideration are: (1) If the injecting of fuel does not impart kinetic energy to the flow, the mixing process, even supposing it takes place in ideal conditions, appreciably lowers the upper limit to the practicability of supersonic combustion (the dissociation limit). (2) As for the lengths required for combustion to take place, the estimate arrived at by this method is practically the same as that obtained by assuming that the mixing and the reaction are two independent processes. (3) In most of the cases considered the diffusion governs the process; in other words, the flow is closer to chemical-equilibrium than to frozen-flow conditions. (Author)
