The transition to GPU based computing software will speed up analysis of rocket engine stands and components used on test stands. This includes cryogenic feed lines, high pressure tankage, valve systems, and cooling spray nozzles on flame deflectors. The algorithms developed here can be extended to NASA codes used for heat transfer analysis, tank pressurization, structural and thermal stress analysis. It will establish GPU porting protocols for engine/facility health monitoring software as well as software used in control systems. The commercial market for our product is very large encompassing the broad markets of aerospace and space transportation, fluid handling machinery (pumps and valves), chemical process plants, nuclear and traditional power generation (gas turbine applications) as well as wind energy. The developed product can also be utilized by the space transportation industry for design support and risk assessment.
