Thermoacoustics

We work to characterise the affect of acoustic instabilities on the burning rate in premixed, non-premixed, and spray flames. Acoustic perturbations in gas turbine engines can significantly augment flame characteristics, leading to stabilisation issues or excited oscillations. This work is aimed at learning the effects of such perturbations on flames in gas turbine relevant geometries and increasing the predictive capabilities of modellers in such systems.
