Abstract

The modeling and experimental investigation of large-scale vortex structures at the exit of a model burner of a low-emission combustion chamber when there is artificial generation of air flow-rate fluctuations are considered. A method for the diagnostics of vortex structures is developed using a two-component laser Doppler anemometer, which enables vortex structures in the jet mixing zone to be distinguished. The intensity of the swirling of the flow is calculated. A simplified rapid method of vortex-structure diagnostics is proposed, which significantly reduces the time of the experiment and the number of measurements required.
