An Investigation of Convective Cooling of an Array of Channel-Mounted Obstacles

Abstract

A numerical investigation of forced convective cooling of an array of obstacles was performed to synthesize the effects of various pertinent parameters on the cooling performance. Reynolds number, channel clearance height-to-element length ratio, spacing-to-channel height ratio, geometric ratio of the blocks, and total number of obstacles were varied to estimate their influence on the cooling process. Two generalized sets of Nusselt number correlations were developed for the obstacles in the channel based on a very large number of computational simulations. The numerical data match the correlation equations quite well.
