THERMODYNAMIC AND ACOUSTIC ANALYSIS OF THE SOLID FUEL PULSATING COMBUSTION IN A HELMHOLTZ RESONATOR TYPE DEVICE

Abstract

One of the perspective applications of pulsating combustion is the utilization of industrial waste. There is a mathematical model and the results of calculating the frequency and amplitude of acoustic gas oscillations in a Helmholtz resonator type device using solid fuel. In this paper, pulsating combustion is considered as a result of the interaction of acoustic oscillations with the process of heat release in the combustion zone. It is shown that the frequency and amplitude of gas oscillations, the amplitude and phase of the heat release rate pulsations, the acoustic energy generated in the combustion zone are interrelated quantities.
