The surface of hypersonic vehicles will have small unavoidable surface features as a consequence of
the integration of the frame. The impact of these features on the surface heating environment gives
rise to key challenges that need to be overcome to allow sustained hypersonic flight. These challenges
deserve study due to the turbulent phenomena, i.e. promotion of transition and/or heat flux
augmentation. Experiments have been performed in the Oxford High Density Tunnel to characterize
the effects caused by such small-scale surface features. This work presents an overview of the
numerical analysis undertaken to support these experiments. The agreement between the numerical
and experimental data is presented. Highlighted is the possibility of numerical methods to allow for
greater parameterization of models in order to support experimental analysis.
