Abstract
In present work, experimental investigation on single phase liquid flow in straight and Divergent wavy minichannels is performed. The objectives are to investigate experimentally, effect of influencing parameters on heat transfer coefficient and pressure drop in these minichannels. Parameters considered are; wave length, amplitude divergent angle of wavy minichannel. The experiments are performed for Re range of 100–500 with water as the working fluid. The measured value of bulk mean temperature and surface temperature are used to calculate the heat transfer coefficient. Experimental results show that Divergent minichannels has significant heat transfer enhancement when compared with the equivalent straight minichannel. It is further observed that increase in heat transfer from 58% to 88% in Divergent wavy minichannels is associated with increase in pressure drop 22% to 35% than the straight minichannels.
