Review: cfd simulation of tapered coil by using silicon dioxide and zinc oxide nanofluid with water and ethylene glycol as its base fluid

Helically coiled heat exchangers are globally used in various industrial applications for their high heat transfer performance and compact size. Nanofluids can provide the excellent thermal performance in helical coil heat exchangers. Research studies on heat transfer enhancement have gained serious momentum 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 efficiency 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 simulate the heat transfer rate in Copper taperedhelically coiled tube heat exchanger using Silicon Di-Oxide and Zinc OxideNano fluid by studying research papers of various authors.
