Abstract - Heat exchanger is a device used to transfer heat between one or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. These exchangers provide true counter-current flow and are especially suitable for extreme temperature crossing, high pressure, high temperature, and low to moderate surface area requirements different Nano partials mixed with base fluids is called Nano fluids and   analysed for their performance of Nano fluids by use  in the heat exchanger. The Nano fluids are Aluminium Oxide, Silicon Oxide and Titanium carbide.The volume concentration of the nanoparticle use in this study is 0.03% and mass flow rate 8 lpm,Nano fluid  inlet temperature  333k and  normal water fluid inlet temperature 300k.   3D model of the compact shell and tube heat exchanger is done in CATIA V5 and CFD analysis is done on the shell and tube heat exchanger by using ANSYS 15.0 fluent work bench. Compare three Nano fluids values for better Nano fluid choose one.
