ABSTRACT:
Nowadays the heat exchanger with higher heat transfer in less area density is the vital requirement of the modern world. A Nanofluid is a fluid which contains nanometer-sized particles, called nanoparticles. Nanofluids are prepared by colloidal suspensions of nanoparticles as additives in a base fluid. The nanoparticles that are used in nanofluids are typically made of metals, oxides or carbides. Nanofluids have attractive thermal properties that make them potentially useful in many heat exchangers because of its superior thermal properties. The development of high-performance thermal systems for heat exchanger enhancement has become popular nowadays. Nanofluids are primarily used as coolant in heat exchangers for the enhancement of its performance such as overall heat transfer coefficient. The performance of heat exchangers using different nanoparticles and its applications have been reviewed and presented in this paper. Study of optimization of the heat exchanger with nanofluid to maximize heat transfer and minimize economic cost is very limited.
