Investigation of Third-Order Closure Model of Turbulence for the Computation of Incompressible Flows in a Channel With a Backward-Facing Step

Abstract

To predict the diffusion process of the Reynolds stresses in reattaching shear flows, the transport model for the triple-velocity products has been developed and tested for the computation of the flow in a channel with a backward-facing step. Upon comparison of the results of uuv , uvv , and vvv with those obtained by using existing algebraic correlations, it was shown that the present model improved the prediction of the triple-velocity products.
