Abstract


Heat exchanger is that device which is used to transfer thermal energy in more than two fluids, between a solid surface and a fluid, at different related temperatures. Heat exchangers are used in various applications and the deserving heat exchangers have major demand from industries. Due to the increasing trend of global industrialization, crucial efforts have been taken to increase the heat transfer, rate of heat transfer, minimize dimensions of heat exchangers, and also increase in the overall effectiveness. The secondary flow develops to the curvature of the tube. The curvature of the coil rules the centrifugal force while the pitch or helix angle creates the torsion subjected to the fluid. The fluid streams in the outer side of the pipe moves heavier than the fluid streams in the inner side of the pipe. The variations in velocity sets-in secondary flows which enhances the heat transfer rate. The main objective of this study is to create the helical coil heat exchanger on the basis of Reynolds number. The performance of any heat exchanger is incremented with the use of helical coil tube structure and it infers that the helical coiled tube heat exchanger is a better solution for the modification over conventional/traditional type of heat exchanger.
