Numerical Simulation of Turbulent Flow and Heat Transfer Over a Backward-Facing Step-A Benchmark Problem
This paper presents the results of a numerical simulation of a two-dimensional, incompressible turbulent forced convection flow in a channel with a backward-facing step. The problem is solved as a benchmark problem for the 1994 ASME Winter Annual Meeting. The Reynolds number and Prandtl number are 20,000 and 0.71, respectively. For a uniformly heated wall downstream of the adiabatic step, the flow and heat transfer characteristics are predicted for different inlet flow conditions and upstream heating levels. A standard turbulence K-Îµ model with wall function is used. Grid refinement is performed to obtain optimum results. A modified TEACH code is used in the numerical computations and the desired flow and heat transfer results are presented for the region downstream of the step.
