Advanced Cooling Techniques for Hydrocarbon Liquid Rocket Engine Components

A useful computational simulation tool will be developed to help systematicallystudy one or more advanced cooling techniques or concepts related to the use of hydrocarbon fuels in rocket engines. A coking model will be added to a general purpose computational fluid dynamics solver. The coking model will be able to estimate wall deposition rates and its effect on the flow quality and stability. The simulation tool developed will be able to help analyse and test advancedcooling techniques for hydrocarbon liquid rocket engines. The benefits can carryover to aircraft engines, where coking also plagues fuel nozzles when propershutdown procedures are not followed. Analogous phenomena arise in blood flowwhere blood chemistry leads to plaque formation and deposition on walls of bloodvessels thereby constraining blood flow. A biomedical equivalent of thecapability developed can potentially be invaluable to medical research.
