Development of Generalized Equations of State and CFD Algorithms for Arbitrary Mixtures of Non-Ideal Fluids

	Marshall Space Flight Center 2005 Phase 3 Development of Generalized Equations of State and CFD Algorithms for Arbitrary Mixtures of Non-Ideal Fluids Tetra Research Corporation/Mississippi State University Princeton, IL/Starkville, MS
INNOVATION Develop and evaluate thermodynamic models suitable for liquids, gases, and supercritical vapors Create generalized algorithms for arbitrary mixtures of non-ideal multi-phase flows	Characteristic LOX Bump Due to Expanding Core Flow Recirculation Can Now Be Predicted Using the Real Fluids Model
ACCOMPLISHMENTS Solved problem of numerical noise in rapidly changing functions near the critical isotherm Improved low temperature predictions near the critical point without affecting high temperature numerical behavior Extended Eulerian dispersed phase capability to support two-way coupled multiphase problems, including particle composition evolution and energy coupling Developed initial framework for extension to Lagrangian multiphase calculations Provided enabling technology for application of CFD to a broader range of injector designs, including performance and environment predictions
COMMERCIALIZATION Supporting ER42 (MSFC’s Fluid Dynamics Branch) with advanced liquid and solid motor analyses Supporting University research programs through the Constellation University Institutes Project (CUIP) activity Software currently in use at Purdue University	GOVERNMENT/SCIENCE APPLICATIONS Liquid engines Solid rocket motors Plume impingement
