Experimental and Investigation of Double Pipe Heat Exchanger Using Fins

Heat exchangers are employed in nuclear and thermal power plants for the heat transfer. Heat exchangers are the major equipments which influence the effective working and overall efficiency of the power plant. So it is necessary to design the heat exchangers with the capacity to transfer maximum amount of heat. The heat transfer mostly depends on the heat transfer surface area and flow direction of the fluids being used for exchange of heat, flow velocity, etc. In this project an attempt is made to enhance the transfer of heat from hot fluid to cold fluid of the double pipe heat exchanger. Here we design a heat exchanger with internal fin which can eliminate more heat. And the comparison was taken with previously designed double pipe heat exchangers. The calculation has been performed as per the standard procedures employed for the design of heat exchangers
