Abstract

The hydrodynamic and heat transfer characteristics of the laminar flow field over a backward facing step are studied numerically both for constant properties and for temperature varying viscosity flows (with water as the working fluid). The two walls are maintained at different uniform temperatures while the flow at the step is assumed to be hydrodynamically and thermally fully developed. Calculations are carried out for different Reynolds numbers in the laminar flow regime. The variation of viscosity with temperature is shown to have a substantial effect on both the reattachment length and the local Nusselt number along both walls, the effect becoming stronger as the Reynolds number increases.
