Baldwin-Lomax model

The Baldwin-Lomax model is a classical algebraic turbulence model which is suitable for high-speed flows with thin attached boundary-layers, typically present in aerospace and turbomachinery applications. The Baldwin-Lomax model is not suitable for cases with large separated regions and significant curvature/rotation effects... more

This article is a good example of a description of a turbulence model. Validation and test cases is the current focus area of CFD-Wiki. So don't hesitate, write something about your favourite test or validation case today!
