Program Facilitates Simulation of Flows of Cryogenic Fluids

EASY/ROCETS is a developmental computer program for mathematical modeling and analysis of dynamic flows of cryogenic fluids in a rocket-engine-testing facility. Heretofore, the numerical simulation of such flows has been accomplished by use of computer codes specific to test-equipment configurations. The complexity of these codes has made it necessary to employ numerical-simulation experts to modify the software for each new configuration. In contrast, EASY/ROCETS is a modular software package that can readily be modified, by choice of modules, for different configurations. Thus, EASY/ROCETS enables engineers who lack advanced numerical-simulation expertise to construct useful mathematical models of test systems, leading to better testing of rocket engines. In so doing, this software also relieves numerical-simulation experts of the burden of day-to-day involvement in modifications of test equipment, enabling them to devote more effort to development of improved component mathematical models that can then be incorporated into the software.
