INVESTIGATION OF ACOUSTIC CASES OF VIBRATIONAL COMBUSTION,

Abstract

The author analyzes intermittent combustion in cases where the excitation mechanism is acoustic in nature, i.e. where disturbances of the combustion process are determined by pulsations in the velocity and pressure of the flow before the combustion zone. Some information on the excitation mechanism may be derived by studying the behavior of the flame with a change in the acoustic properties of the channels before and after the combustion zone. Formulas are derived for determining the amplitude-phase characteristics of 'transfer functions' of the combustion zone. These relationships may be used for studying the properties of non-stationary oscillations during flame propagation. (Author)
