| Regenerative fuel cooling is being used as an enabling technology for next-generation propulsion systems for high speed (>Mach 5) flight. The heating load is partially absorbed by the endothermic fuel, inducing a transition from a liquid phase to a supercritical-fluid phase. The injection of the fuel into the combustor involves the expansion of the supercritical fluid through a small orifice, which may be accompanied by liquid droplet formation, turbulent mixing, and shock waves. This paper will survey recent work in simulating the injection of supercritical fuels through solution of the Navier-Stokes equations governing a multi-phase mixture of fluids. Results will also be presented for aerated-liquid atomization, which is used to accelerate the primary breakup of the fuel stream. Work performed with Dr. Carbonell on the use of the RESS process for depositing polymeric coating materials led directly to these capabilities, and this connection will be specifically highlighted in the paper. |
