Abstract

In this paper the database obtained from LES is used to examine the algebraic turbulence model in Demuren and Rodi’s work. The results show that the prediction of normal Reynolds stresses and turbulence energy by means of turbulence modeling is better than that of shear Reynolds stresses. The comparison shows the LES method can be used to examine turbulence modelling.
