Thesis Title

Large-eddy simulation for prediction of sound generation by turbulent premixed flames

Research overview

Predicting flame acoustics using Large-eddy simulation (LES) is of interest in the design and operation of gas turbine combustors. This is mainly because flame-generated sound can trigger thermoacoustic instabilities, leading to damaging pressure oscillations that pose severe danger in gas turbine operation. Modern gas turbines using lean premixed combustion to reduce NOx emissions are particularly susceptible to these instabilities. This project studies the ability of LES combustion modelling based on the concept of flame surface density to predict sound generation by turbulent premixed flames, to assist the design process of cleaner gas turbines.
