dc.description.abstractThis paper presents a heat removal study on triangular and square ribbed surfaces under an array of impinging airjets. The investigation was carried out using nozzles with a 7x3 rectangular array of circular jets. The effect of Re number,jet-to-plate distance, and rib arrangement on heat transfer and fluid flow characteristics was examined numerically. Twoarrangements have been studied. Arrangement A considers the situation when the cooling jets are directed towards the ribs,while arrangement B considers the situation when the jets are directed towards the centre line of the cavity between two ribs.Wall jets of neighboring jets have a stronger interaction with increasing Reynolds number. The lowest and highest local heattransfer for all rib geometries was obtained for H/d=8 and H/d=4-6, respectively. On triangular ribbed surfaces the stagnation point Nusselt number values for arrangement A are significantly higher than the stagnation point Nusselt numbers for arrangement B.
