Abstract

In this study, numerical investigation on heat transfer by mixed convection for air-cooling through a rectangular horizontal duct with three heat sources is conducted. These heat sources are rectangular ribs with different small aspect ratios and every heat source emits uniform heat flux with small space between each other. The investigation is to enhance forced convection that produced from fan through a rectangular horizontal duct with natural convection using perforated holes between each heat source. The study shows the effect of air entering through the holes at different open hole ratio β (0.01472, 0.02618, 0.04091, 0.05891, 0.08017) and with Reynolds number Re in the range (376, 900, 2073, 3428 and 6170) and at Grashof number Gr = 0.371 x 107 on the temperature of each heat source. The results show the best performance at open hole ratio 0.04091 for which the dimensionless temperature decreased by 5% for the first heater, 15% for the second one and  6% for the third one.
