Combustion of Two-Phase Mixtures

Abstract

A study was made of the gas-dynamic stability of the propagation of detonation in an aerosol and the combustion of a solid fuel with respect to one- dimensional perturbations of the exponential type. The internal structure of the processes studied is centrally considered, and from an analysis of the mechanical interaction of the structure with spontaneous perturbations, feedback equations are derived for each case. The system of boundary conditions controlling the perturbed states of processes is based on the successful application to the zones of their occurrence of fundamental theorems of hydrodynamics concerning change in mass, in momentum, and in energy. As a result, analytic criteria of instability are found, delimiting the region of the possible existence of steady-state regimes of the processes being analyzed and indicating ways of stabilizing the pulsations that arise.
