Abstract

Two hypersonic computational fluid dynamics (CFD) codes, the NASA Ames code DPLR (Data-Parallel Line Relaxation) and the NASA Langley code LAURA (Langley Aerothermodynamic Upwind Relaxation Algorithm), are being used to generate the aerothermodynamics database for the NASA Constellation Program Crew Exploration Vehicle (CEV) named Orion, the new spacecraft for human space exploration. Both codes are used to simulate the aerothermal environments that Orion will experience for the purpose of designing its thermal protection system (TPS). The CEV Aerosciences Project (CAP) has supported the present comparison study between the two codes for the Apollo era flight test, FIRE (Flight Investigation of Reentry Environment) II, to investigate and quantify the differences in convective and radiative forebody heating predictions. In addition, the parallel unstructured implicit Navier-Stokes solver US3D of the University of Minnesota participates in the present study. Results indicate at most a 7% difference in the predicted forebody convective heating levels. The radiative heating predictions however indicate substantial disagreement for the vacuum ultraviolet (VUV) range.
