Abstract

Finned-tube heat exchangers are one of the types of heat exchanger in which it is one of the most and vital components in many energy systems such as heating, ventilating, refrigeration and in air conditioning systems. In recent days many advancement in the heat exchanger have been done in order to increase the heat transfer rate in which nanofluids play a major role in today’s research. A nano fluid is a fluid containing nanometre sized particles, called nanoparticles. These fluids are engineered colloidal suspension of nanoparticles in a base fluid. Nanofluids have special properties that make this fluid to potentially useful in many applications in heat transfer system, in domestic refrigerator, in heat exchanger and so on. This paper reveals the characteristics performance of fin and tube heat exchanger by using various Nanofluids and there by analysing the corresponding heat transfer rate for different Nanofluids. Since the nanoparticles used in Nanofluids are typically made of materials such as metals, oxides, carbides, or carbon nanotubes.
