Heat transfer has a crucial importance in the engineering applications; therefore, various methods for enhancing the heat transfer have been proposed by the researchers and new methods have been developed in recent years. One of these methods is using nanofluids. Nanofluids have enhanced thermal properties in compare with the base fluid. In this paper, the latest studies on the use of nanofluids in the double tube heat exchangers and shell and tube heat exchangers with description of the test system has been evaluated and the results have been summarized. In the end, the results of using shell and tube heat exchangers as a bed for exothermic reactions in the process of Fischer-Tropsch synthesis using nanofluids is provided. In all of the work done by increasing the nanoparticles volume fraction and the Reynolds number, the heat transfer coefficient and process efficiency have increased.
