The tools developed in this SBIR project will be directly useful to NASA's Hypersonics Program. The methods developed under this project will have wide ranging applications at NASA in addition to high-speed combustion devices such as ramjets and scramjets, including design of propulsion devices such as solid rocket motors, liquid rocket engines and gas turbine combustors important in the design of the Space Launch System, In-space propulsion systems, numerous planetary spacecraft missions, etc. The Eulerian transported PDF methods are an area of active research and have excellent promise to provide accurate and computationally tractable models for complex turbulence-chemistry interactions. The software tool developed in this project will significantly improve the accuracy and reduce turn-around times for design and analysis cycles for scramjet applications to the Department of Defense programs. It will also be useful for simulating low-speed combustion devices such as gas turbine combustors and augmenters. The technology will facilitate significant advancement in use of CFD analysis in applications including propulsion devices, gas-turbine combustors and other combustion devices. The software will be beneficial to OEMs such as GE, Pratt & Whitney, Williams International, and Rolls Royce in designing various propulsion devices and gas turbine combustor components. It will be a valuable tool for all industries that require CFD simulation of reacting flows in a hardware design process. Modules developed in this project will also be of interest to commercial CFD OEMs such as ANSYS for integrating with their own simulation software.
