The proposed computational tool will be of direct use to NASA's current and potential OEM contractors for liquid rocket engines (Pratt & Whitney-Rocketdyne, ATK-Thiokol, AMPAC-ISP, Aerojet, and others). It will also be beneficial to gas turbine engine and diesel engine manufacturers, and has applications in fuel injector design for power plants and in industrial boilers/burners. The tool will also be relevant to chemical industry applications involving flows with phase change, phase separation, and heat and mass transfer. Improved Cryogenic Fluid Management (CFM) can also play a key role in infrared and x-ray astronomy, and biological sciences. The proposed VOF module in Loci-STREAM will enable NASA and government contractors to better analyze and design liquid rocket engines. These applications include: (1) Sloshing of liquid fuels in fuel tanks; (2) Extrapolation of slosh experiments to cryogenic fluids; (3) Propellant tank stage separation dynamics; (4) Design of anti-vortex baffles; (5) Thrust oscillation impact on the upper stage ullage collapse; (6) Water pooling dynamics associated with launch pad environments mitigation using water deluge; (7) Propellant tank pre-pressurization, re-pressurization and self-pressurization processes, and many others. The software will help achieve better Cryogenic Fluid Management (CFM), which is an integral part of exploration systems for Earth-to-Orbit Transportation, in-space fuel depots, planetary exploration missions, and In-Situ Resource Utilization (ISRU) systems.
