A numerical study of laminar flow and heat transfer over a two-row and three-dimensional slit fin and tube heat exchanger is presented. The effects of two different slit numbers Sn = 2 and 4 are investigated in detail for the Reynolds number ReH (based on the fin spacing and the frontal velocity) ranging from 160 to 900. The numerical results for the velocity field, fin surface Nusselt number, Colburn and fanning factor are shown. It is found that, both the average Nusselt number and pressure drop coefficient are increased as the slit number Sn is increased. A comparison of the numerical results with the available experimental data is also presented.
