Experimental Investigation of Shell and helical coiled tube heat exchanger using TiO2-Water based Nanofluid

Shell-and-coil heat exchangers have been used mainly in solar domestic hot water (SDHW) systems because of their high heat transfer and smaller space requirement, their use is also in heat recovery systems for space heating. This project deals with the performance analysis of the shell and helical coiled tube heat exchanger to improve the performance of helically coiled tube heat exchanger using Nanofluid. In this project work, the heat transfer analysis on shell and helical coiled tube was done experimentally using water and TiO2-water Nanofluid at 0.5 % volume concentration. It was found that the performance of heat exchanger was increased while using Nanofluid as compared to that of water. It was found that the use of Nanofluid enhances the convective heat transfer coefficient and overall heat transfer coefficient significantly
