Abstract

Experimental measurement of flame response to acoustics under conditions relevant to industrial engines is challenging and so the scope of such measurements is often limited. High fidelity CFD can be used to model the interaction of acoustic waves with cryogenic flames, and modelling an experimental test case can not only serve as a code validation exercise but also be useful in better characterising the experimental results. This work explores this potential by extending the interpretation of high-speed imaging of representative rocket flames based on comparison with a large eddy simulation of the experiment.
