A Numerical Simulation and Visualization for Turbulent Flows in Two-Dimensional Cavity

Abstract

In the present paper, a finite difference numerical procedure of the standard version of k-ε turbulent model has been conducted to predict the turbulent flow in a two-dimensional square cavity for Reynolds No.=10 ⁴-4×10 ⁴. The formulation of wall function is simplified to evaluate the variables adjacent to wall in the present calculation. Furthermore, the calculation of the cavity flow with resistance has been performed. In comparison with several flow patterns of visualization by using a laser sheet, a reasonable agreement has been obtained.
