CFD Analysis of Cone Shaped Coil Heat Exchanger by Using Copper Oxide Nanofluid with Ethylene Glycol and Water as Its Base Fluid in Aluminium Tube with Different Mass Flow Rate

Abstract

Abstract: The recovery of waste heat has been a topic of concern for large-scale industrial companies for several decades. This recovery not only makes an operation more environment friendly, but it also helps to cut costs. In addition to this, it can reduce the amount of resources needed to power a facility. Many industries have implemented different methods of waste heat recovery. In this present paper the efforts are made to understand that how to compare the heat transfer rate in Cone shaped coiled tube heat exchanger using CuO Nano fluid with Water and Ethylene glycol as a base fluid in Cone shaped Heat Exchanger with the help of CFD on aluminium tube. Cone Shaped coil was fabricated by bending 500 mm length of aluminium tube having 10mm tube diameter, 50 mm pitch coil diameter, 25mm pitch and tapered angle 20 . The comparison of pressure drop and temperature variation between different mass flow rate with water and ethylene glycol as its base fluid in aluminium tube found in this analysis. The result indicates that the CuO nanofluid with ethylene glycol as a base fluid at 0.02m/s mass flow rate have maximum pressure drop and also have minimum temperature variation compare with other mass flow rate.
