Abstract : The heat exchangers are used to enhance heat transfer by providing high heat fluxes or heat transfer coefficient. The second law efficiency increases and the entropy generation decreases by reducing the temperature driving force which is caused with the increase in heat transfer coefficient. The present experimental work is carried out with copper and aluminium serrated plate by varying groove (slot) thickness from 6mm to 8mm and by varying thickness of plate from 3mm to 5mm respectively. The inserts when placed in the path of the flow of the fluid, create a high degree of turbulence resulting in an increase in the heat transfer rate and the pressure drop. The work includes the determination of friction factor and heat transfer coefficient for various inserts with varying thickness and different materials. The results of varying thickness in serrated plates with two materials are compared with the smooth tube and found that copper with 5mm thick and 6mm serrated slot has optimum results in terms of heat transfer coefficient and friction factor.6mm slot and 5mm plate thickness copper shows higher Nusselt number of 60% to 76% and lesser friction factor by 39% as compared to without inserts. Keywords- Enhancement efficiency, heat transfer, serrated plate inserts, turbulent; swirling, pressure drop.
