Introduction One of the key considerations to the accuracy of CFD prediction is turbulence modelling for most of practical applied aerodynamics. The Baldwin-Lomax algebraic turbulence model (BLM) [1] is the most popular turbulence model for applied compressible aerodynamics and has been used even in very demanding flow fields such as separated flows and high supersonic flows. More complex turbulence models are introduced for better accuracy for such cases but with much higher computing times and therefore costs. The Johnson-King turbulence model (JKM) [2, 3] is recently being used for applied CFD
