Abstract
The working group planed to carry out the cross comparison of CFD results of flow around building model with shape by various k-e turbulence models in order to investigate the performance of revised k-e turbulence models in the same condition. Results of the analyses were compared with experimental data. The standard k-e model overestimated turbulent energy in flow with Impinging. This drawback was corrected by all revised k-e models tested here. But revised k-e models overestimated the reattachment length behind the building in comparison with the standard k-e model.
