Heat Transfer Effect of CNT and Ethylene Glycol Based Nano-Fluid in Twisted Tape Heat Exchanger with Balls

Heat transfer improvement is the main parameter in a heat exchanging equipment. Few methods to increase the
coefficient of heat transfer is by creating the turbulence in heat exchanging elements and changing the heat transfer
fluids. For current analysis of tube heat exchangers, tape inserts containing balls are implemented with nano-fluids in
Carbon Nano Tubes (CNT) and ethylene glycol. 3D modelling and simulation of twisted tape heat exchanger with balls
were carried out using Solidworks and ANSYS Workbench. Heat transfer rate, friction factor, temperature difference in
the heat exchangers, Reynolds number and Nusselt number variations are assessed in this work.
