Periodic fully developed fluid flow and heat transfer characteristics are obtained numerically for turbulent flow over a three-dimensional array of heated square blocks deployed along one wall of a parallel-plate duct. This configuration simulation forced convection cooling of electric equipment. The Lam-Bremhorst low-Reynolds-number form of the k [minus] [epsilon] model is used for the computations. The computations are performed for a set of geometric parameters characterizing the array, for a range of Reynolds numbers from 10[sup 3] to 10[sup 4], for a Prandtl number of 0.7, and for a condition of uniform wall temperature. The results are compared with relevant experimental data from the literature wall temperature. The results are compared with relevant experimental data from the literature and also with the numerical values obtained by using the high-Reynolds-number form of the k [minus] [epsilon] turbulence model.
