CFD Analysis for Heat Transfer Enhancement Using Nano Fluids in Double Pipe Heat Exchanger

This work includes the effect of different working fluid on the performance of heat exchanger. For analysing the effect of different working fluid, it considered air, water and different nanofluids and measure the Nusselt number and friction factor for each case. It also analysed the effect of change in Reynolds number on the performance of heat exchanger for different working fluids. For analysing the effect of change in Reynolds number, it considered four different Reynolds numbers that is 10000, 12000, 14000 and 16000. For performing the numerical analysis ANSYS fluent was used. Through numerical analysis it is found that for air as a working fluid heat transfer is less, whereas in case of water it is marginally higher than the air. But for all nano fluids, heat transfer is much higher than the air and water. For analysing the effect of different nano fluid, this work includes three nano fluids that are Al2O3, TiO2and ZrO2. Through analysis it is concluded that heat transfer is more in case of TiO2 as compared to other nanofluids, air and water. With increase in Re number heat transfer gets increase whereas as friction factor get decrease.
