Multi-disciplinary Multiphase Flow Analyzer

Simulation methodologies which describe complex, Multiphase, flow phenomena including cavitation, cryogenic fluid management, coolant spray and impinging jets will be developed. Accurately described real fluid properties will be employed in an integrated simulation tool, that involves thermodynamics and fluid dynamics models, to describe local vaporization phenomena in liquid rocket engine propellant delivery systems, propellant tanks and the test facilities. Bubbly flows will be simulated with a homogeneous or heterogeneous mixture model, which emphasizes the computational efficiency and modeling effectiveness. Cavitating venturi meter and pump flows, cryogenic propellant tank filling processes and evaporating cooling jets can be analyzed with this methodology. More accurate propellant metering, oscillatory inlet flow characterization and accurate description of the thermodynamics environment of cryogenic fluid systems will be the result of this project. Other complex flows in propellant delivery systems or coolant flows in test facilities will also be amenable to analysis with the produced methodology.
