Abstract

The development of future rocket engine or gas turbine technologies, intended to respectively reduce the costs of access to Space and pollutants emissions, requires a thorough understanding of combustion instabilities in order to be able to predict and avoid them. This work explores several directions to meet these expectations. The first is the introduction of a new class of low-order numerical methods, which allows the resolution of thermoacoustic modes in complex combustion chambers. These emerging numerical methods gave birth to STORM, a software package intended to assist aeronautical industry engineers during the design of new engines. The second direction followed is the study of the flame dynamics characteristic of liquid-rocket engines. These high-fidelity simulations revealed the mechanisms governing the oscillations
of such a flame during its interaction with a combustion instability.
