Computational fl uid dynamics (CFD) has brought a step change in the fi eld of fl ow analysis, particularly in the areas of fl uid dynamics and heat transfer, which are intertwined. It has carved a niche in applications where, a decade back, experimentation was the only way forward. This article covers the benchmarking of convective heat transfer cases through the use of CFD software. The cases investigated are common cases of heat transfer involving free convection and one case involving forced convection. The results from CFD analysis are compared with the regressions available for each test case. The two sets of data coincide well, with a percentage difference as low as 0.4%. Information on setting up CFD analysis accurately, particularly for solving problems of natural convection, is also included.
