Abstract :

As pressure and temperature in the propulsion system increase to enhance performance, the injection of fuels or propellants finds themselves under supercritical conditions which pose challenges both from experimental and computational perspectives. This work intends to present a review of the state of knowledge in the context of fuel or propellants injected into the combustion chamber. As an example, in cryogenic H2/LOX liquid rocket engines, such as Space Shuttle Main Engine (SSME) or Vulcain (Ariane 5), the injected liquid oxygen (LOX) finds itself in a supercritical condition. Improved understanding of the fluid injection physics under such conditions are needed for the better design of such propulsion systems.
