Abstract: : In this paper, performance of minichannels having natural leaf like structures are studied numerically and experimentally. Here the effect of change in bifurcation angle of secondary veins along with different aspect ratios on heat transfer is studied numerically. Bifurcation angles 15o , 20o and 27o with aspect ratios 2 3 and 4 are analysed numerically with heater input of 30w , 40w ,50 w and varying Reynold’s number from 200 to 800. Their performance is also compared with conventional parallel mini channel It is found that maximum heat transfer coefficient and Nusselt number is obtained for the geometry having bifurcation angle of secondary veins as 15o and aspect ratio 2. The results are then verified experimentally with conventional parallel minichannel with aspect ratio 2 and natural pattern minichannel having bifurcation angle of secondary veins 15o and aspect ratio 2 are tested for heater input of 20 w, 40 w, 50, w and Re 100, 200, 300, 400 , 500 and 550. The values of heat transfer coefficient and Nusselt number values are found experimentally and numerically for both the minichannels and are found close to each other with experimental values are found slightly lower than values got by numerical analysis . Also it is found that there is improvement in heat transfer coefficient and Nusselt number values for natural pattern minichannel heat sink compared to straight minichannel heat sink thus showing heat transfer enhancement
Keywords: - natural pattern, aspect ratio, bifurcation angle
