Heat exchanger is a device to transfer heat from one medium to another medium. In order to increase the heat transfer rate many researcher optimized different process parameters of heat exchanger. Due to the reduction of size of heat exchanger there is a pressure on designer to increase heat transfer per unit area of heat exchanger. Now day metal oxide particles of nano size were used to make nano fluid which increases the heat transfer rate inside the heat exchanger. Here in this work we have calculated the effect of different nano fluid on heat transfer, for calculating the effect of different nano particle here we have considered three different nano particles that is Aluminium oxide (Al2O3), Ferric oxide (Fe2O3) and Copper oxide (CuO). Here we have also calculated the effect of different percentage of nano particles in nano fluid, for calculating the effect of different percentage of nano fluid here we have considered two different volume percentage of nano particle that is 0.25 and 0.5 %. Through analysis it is found that copper-oxide nano fluid shows maximum heat transfer as compared to other nano fluids. CuO nano fluid shows 8% more heat transfer than the Al2O3, whereas CuO shows 39.90% more heat transfer as compared to Fe2O3.
