This paper studies the heat transfer properties of a helical coiled heat exchanger by the use of nanofluids to enhance these properties. The analysis compares these properties for two different nanoparticles suspended in water to determine which gives a better result and also economical to use. Copper oxide and aluminum oxide nanoparticles suspended in water were used and the results were also compared with water as a working fluid for the heat exchanger. Analysis was carried out using CFD software, Ansys fluent 16.0, and the heat exchanger was also modeled using Solidworks 2016. The results were validated by carrying out the CFD analysis of a heat exchanger with known results, the CFD results were compared to prove that it is a reliable tool for thermal analysis.
