In heat exchanger heat is transfer from the higher to lower temperature difference and transfer of heat is an important aspect of the heat transfer application. The efficiency is depending upon the amount of transfer heat and mode of heat transfer. Heat is transfer from hot to cold fluid through wall max heat can transfer based on the heat transfer coefficient of transferring medium and the thermal conductivity of material. To increase efficiency heat transfer between small temperatures should be increased; this can be done by increasing the efficiency of the working fluid. In this experiment, heat transfer from hot fluid to cold fluid by Double pipe heat exchanger is experimentally investigated by using different Nano particles like Al2O3, CuO, SiO2, Ethylene-glycol and Water to get better heat transfer, the same thing is validated in CFD analysis. The experiment is performed at Laminar flow under different flow arrangements like Parallel flow and Counter flow. Same flow variations are validated in CFD analysis.
