Abstract

High-fidelity modeling tools are essential for accurate predictions of planetary entry. The same tools can also be used to interpret ground test data. A hypersonic aerothermodynamic computational fluid dynamic code is used to compute the flowfield of a high-enthalpy flow facility, and the results are compared to published experimental data. A test case is selected that consists of a 6.5MJ=kg bulk enthalpy flow that discharges into a vacuum chamber at 0.228 kPa. The simulation parameters are compared to radial and axial velocity profiles. Surface pressure and heat flux profiles are analyzed, and excellent agreement is found with the experimental data. A parametric study is carried out in order to better assess the effects of the initial and boundary conditions.
