Nicolas Rutard's PhD thesis
The aim of these simulations is to gain a better understanding of the interaction mechanisms between acoustic disturbances and the liquid jet atomization process (jet deformation, atomization intensification). These mechanisms may play an important role in the occurrence of high-frequency combustion instabilities in liquid-propellant rocket engines. Advanced numerical models and methods dedicated to multiphase flows developed at ONERA enable high-fidelity simulations to be carried out to complement experiments.
