Nanofluids have evoked immense interest from researchers all around the globe due to their numerous potential benefits and applications in important fields such as cooling electronic parts, cooling car engines and nuclear reactors. Numerical study of concentric double tube heat exchanger has been investigated numerically using two-phase approach. Nanofluids that are used as coolants flowing in the outer tube while hot pure water flows in inner tube. The study will be conduct for Reynolds numbers ranging from 10,000 to 50,000 and nanoparticles volume fractions of 2, 3, 4 and 6 percent. The three-dimensional governing equations are discretized using the finite volume approach. For this study, nanofluid consisting of Al2O3/water is used. From this simulation will be find the better enhancement in heat transfer and also predict other parameters influence for enhancing the heat transfer other than thermal conductivity of nano fluids
