Abstract

Ignition and pressurization of the combustion chamber are the most critical phases of a rocket's launch. The aim of this work is to study these phenomena for a coaxial GCH4/G02 injector representative of space applications. A simulation of this transient has been performed with a commercial CFD program, CFD++, using a one-equation LES and a model of real gas. Acoustic analysis performed during the transient determines the main oscillatory modes driving the coupling between combustion and fluid dynamics.
