  • Abstract:
  • Heat exchanger is a specialized device that assists in the transfer of heat from one fluid to the other. In this paper we considered the parallel type of flow arrangement, were the fluids come in from the same end & move parallel to each other as they flow to the other side. The following design parameters are Baffle spacing, Baffle cut, type of baffles, tube arrangement (inline), and single pass. The rate of heat transfer in heat exchanger is the phenomenon depending on the flow characteristics of shell side fluid. The solution of the proposed problem will be done using CAE technique. The solution of the problem will be done using CFD. The results from the CFD software will be compared with analytical solution to draw the conclusion. The following conclusions were drawn. The tube side flow doesn’t vary in its flow characteristics irrespective of the baffle cut, but due to the variation of rate heat transfer on the shell side in turn affect the tube rate of heat transfer also. With the increase in the baffle cut rate of heat transfer decreases (3 to 25 %).With the increase in the baffle cut Pressure drop increases (3 to 25 %).The velocity over the length of the heat exchanger on shell side gradually increases from entry to exit compartment.
