Abstract

A computational parametric study of forced convection in two-dimensional ribbed channels was performed. The effects of Reynolds number, element (rib) height, element width, element-to-element spacing and the variation of heat flux distribution of the elements on the average Nusselt number and heat transfer coefficient were determined numerically using commercial Computational Fluid Dynamics package. The results were compared to experimental data obtained from the literature and showed good agreement. Based on this study, the average Nusselt number was correlated to each variable parameter using regression analysis. It was found that the Nusselt number is a strong function of geometric parameters and flow velocity. A major finding of the numerical study was the negligible effect of heat flux profile on the average Nusselt number.
