Paper Abstract

The paper presents the experimental study results on the effect of external pressure fluctuations on the temperature field in a flame during the combustion of certain liquid hydrocarbon fuels. It is determined that the height of the flame is changed with an external effect occurrence in the form of small amplitude pressure pulsations. Identified oscillations correspond to the frequency of external sound exposure in the spectrum of flame temperature change.
