Abstract

This article presents a numerical investigation of the heat transfer behavior between a symmetric and staggered arrangement of three discrete heat sources in an open-ended vertical channel under non-uniform heating and non-Boussinesq conditions over a range of modified Rayleigh number (Formula presented.) to (Formula presented.) The staggered arrangement shows an improvement (Formula presented.) and a decrease ((Formula presented.)) of Nusselt number on the left and right wall respectively but overall cooling enhancement over the symmetric arrangement, with linearly increasing heat flux condition showing maximum enhancement. Correlations of the heat transfer and flow rate with modified Rayleigh number for the staggered arrangement are presented.
