Numerical simulation of transitional flows with laminar kinetic energy

Abstract eng:
The article deals with the numerical solution of transitional flows. The single point k-kL -ω model of Walters and Cokljat (2008) based on the use of a laminar kinetic energy transport equation is considered. The model doesn’t require to evaluate integral boundary layer parameters (e.g. boundary layer thickness) an is therefore suitable for implementation into codes working with general unstructured meshes. The performance of the model has been tested for the case of flows over a flat plate with zero and non-zero pressure gradients. The results obtained with our implementation of the model are compared to the experimental data of ERCOFTAC.
