On the Validation of a Hypersonic Flow Solver Using Measurements of Shock Detachment Distance
When using computational fluid dynamics (CFD) codes for computing quantities for engineering purposes, it is important to have confidence in the accuracy and quality of the code. Hence, it has become important to verify and validate CFD codes. Verification refers to ensuring that the numerics of the flow solver are correctly solving the chosen set of governing equations. Validation, on the other hand, is used to check that the governing equations and associated models are appropriate to capture the physics of interest in the flow. In this paper, we undertake a validation exercies for a hypersonic flow solver for chemically reacting flows by comparing computations of shock detachment distance on spheres to experimental measurements. The particular flow solver validated is Eilmer, which has been developed (and continues to be developed) by researchers at the Centre for Hypersonics at The University of Queensland.
