Next generation Space Launch Systems are being designed at NASA for access to space. These include launch configurations for earth-to-orbit to access the International Space Station and to launch modules for eventual landing on asteroids and moons and entry into the Mars atmosphere. Design of new and powerful propulsion systems will be a major requirement for this new generation aerospace flight hardware. Launch pad design, with rocket plume trenches, for these new booster configurations also requires high fidelity base flow and heating predictions. Our proposed program addresses the time-critical technology development item by providing a new anisotropic meshing code to address high Reynolds number viscous flow fields. The software to be provided in this SBIR project is a computational capability which is critical for design and analysis of these next generation space vehicles. There are important commercial problems that can directly use and benefit from the application of our software. Some example industries and applications are: Analysis of nuclear blast accidents from power plants: Automobile manufacturers for design of car and truck engines, transmissions and issues including engine cooling, under-hood flows, and air bag design: Airline companies who are responsible for maintaining safe flying machines: Watercraft design for safety concerns: Bio-Medical applications such as blood flow in elastic arteries, hearts, and air flow in lungs: Computer simulation of blast waves for use in anti-terrorists investigations: Housing design for protection from hurricanes, and tornados: The entertainment industry and film makers for taping building and bridge collapse, bombs blowing up buildings, and storms destroying structures: Heating and air conditioning manufacturers for home units, large office complexes and automobile air conditioning systems.
