Review: comparison on cfd analysis of tio2 nano-fluid with water and ethylene glycol as a base fluid in tapered helical coil heat exchanger

Helically coiled heat exchangers are globally used in various industrial applications for their high heat transfer performance and compact size. Nanofluids can provide the superb thermal performance in helical coil heat exchangers. Research studies on heat transfer enhancement have gained solemnmotion during recent years and have been proposed many techniques by different research groups (1). A fluid with higher thermal conductivity has been developed to increase the proficiency of heat exchangers. The dispersion of 1-100nm sized solid nanoparticles in the traditional heat transfer fluids, termed as nanofluids, exhibit substantial higher convective heat transfer than that of traditional heat transfer fluids. Nanofluid is a heat transfer fluid which is the combination of nanoparticles and base fluid that can improve the performance of heat exchanger systems. In this present paper the efforts are made to understand that how to compare the heat transfer rate in Tapered Helical Coil by using TiO2 nanofluid as water and ethylene glycol as a base fluid by studying research papers of various authors.
