PREDICTION OF TURBULENCE FLOW WITH EFFECTS OF STREAMLINE CURVATURE

摘要

A mathematical model for predicting turbulence flows with effects of streamline curvature under orthogonal curvilinear coordinates is developed in this paper. The SIMPLEC solution procedure has been used for the transformed governing equations in the transformed domain. The Loci of flow reversal of the seperated flows over a backward facing step are employed to test the capability of the proposed turbulence model in capturing the effects of local curvature. The comparision between the computed results and experimental data shows a satisfactory agreement.
