Abstract: In this paper the database obtained from LES is used to examine the algebraicturbulence model in Demuren and Rodi’s work. The results show that the prediction ofnormal Reynolas stresses and turbulence energy by means of turbulence modeling isbetter than that of shear Reynolde stresses. The comparison shows the LES methodcan be used to examine turbulence modelling.
