Abstract
Computational Fluid Dynamics (CFD) is used extensively in modelling high-speed flows for commercial transport aircraft. Current production CFD has deficiencies in modelling specific flow features. In this paper unitary flow cases are considered for specific flow features such as boundary layers, vortical flow, flow separation and shock boundary layer interaction. In the paper new CFD practices in meshing and turbulence modelling are investigated in order to better represent these flow features. In order to measure improvements metrics are introduced which measure an improvement with respect to a reference (from wind tunnel experiment or LES computation). In the paper it is shown that application of new CFD practices give an improved prediction of boundary layer and vortical flow.
