The current research aims at analyzing the heat transfer rate of the nano particles with double tube heat exchanger. Graphene, the nano particle under consideration, can be prepared using Hummers and Offeman method. The analysis has been done with the help of Ansys14 Fluent software. The physical properties (density, thermal conductivity, specific heat, viscosity) of the nano particles are taken from a standard journal and analyzed in a double tube heat exchanger. The simulation is done using the Ansys fluent for a particular concentration of graphene and the results are found to be almost similar. Hence the result obtained is standardized. The analysis is done for various concentration of graphene i.e. graphene 1(0.07% by weight) and graphene 2(0.080% by weight) with corresponding properties and analysis has been continued by making grooves on the outer surface of the inner tube in case of double tube heat exchanger. It has been found that the performance and heat transfer rate of double tube heat exchanger with grooving is better than that of without grooving.
