The commercial market for our product is very large and includes the broad market of rapid response control valves in industries such as nuclear power generation, chemical process plants, and hazardous waste facilities among others where the transient performance characterization of valves play a vital safety role. In addition to these traditional markets, commercial space ventures ranging from space transportation systems (COTS) for the international space station (ISS), to low-cost satellite launch systems are getting an infusion of venture capital and would be receptive to accurate simulation tools. The primary market for this product will be in the design and analysis of high-performance, high-reliability valves used for inherently transient operations in the nuclear and chemical process industry. Here characterizing the transient performance is a critical safety issue and the availability of a well-validated, reliable computational tool can play a key role in the design process for these critical elements. The end-product will be a high-fidelity, numerical simulation software (CRUNCH CFDREG
code) that would predict the transient performance of flight valve configurations, provide design support by supplementing current empirical rules, and diagnose system anomalies. Our product addresses core needs of NASA in the Constellation program, and the mission to the moon, for reliable and well-validated computational tools that can provide accurate simulations of performance in an accurate and efficient manner to be useful within a design cycle timeline. The technology developed here would directly impact analysis of the valves and the feed systems to be designed for the upper-stage J-2X feed system in the Ares 1 launcher by providing the transient mass flow through the valve, unsteady torque loads on the actuator controlling the valve, as well diagnosing the potential for damaging water-hammer as well as multi-phase cavitation effects that may result during rapid on-off control.
