The capability of Computational Fluid Dynamics (CFD) software to accurately predict hypersonic shock wave laminar boundary layer interactions is examined. A series of independent computations performed by researchers in the US and Europe are presented for two generic configurations (double cone and cylinder) and compared with experimental data. The results illustrate the current capabilities and limitations of modern CFD methods for these flows.

Modern computational fluid dynamics (CFD) codes used for numerical simulations employ various models that describe physical phenomena such as energy relaxation, chemical reaction rates and diffusion processes. Additionally, novel algorithms have been developed for the
