Cryogenic fluid flow modeling at NASA's Stennis Space Center

Computational models for dynamic fluid flow simulation are needed to predict pressures, temperatures, flowrates, and other quantities in present and future testing at the Component Test Facility (CTF) at NASA's Stennis Space Center (SSC). The Rocket Engine Transient Simulation (ROCETS) package, and Boeing Computer Services' EASY5x are the two major components of the EASY/ROCETS dynamic fluid flow simulation package, which has been developed by Mississippi State University personnel for use at SSC. This paper presents the results of preliminary modeling of the CTF at SSC, and discusses and demonstrates the use of EASY/ROCETS to model various control system strategies for the high pressure hydrogen (HPH2) subsystem of the CTF
