e 17 Simulations of three-dimensional laminar forced convection adjacent to inclined backward-facing step in rectangular duct are pre-region and inside the reverse flow regions vary greatly. For example, the minimum wall shear stress and the maximum heat transfer rate occur in the neighborhood of reattaching the corner where the sudden change in geometry starts. tures of flow and heat transfer in this geometry, and it has been used in benchmark studies for validating two-dimen-sional simulation algorithms/codes and equipment (see, for example, [1–3] and the references cited therein). Simula-tions and measurements of flow adjacent to the 2-D back-ward-facing step geometry have appeared extensively in the * Corresponding author
