Design and CFD analysis of hair pin heat exchanger using aluminium and titanium carbide nanofluids

Abstract

Heat Exchangers are primarily used for transfer the heat. Design of heat exchanger is one of the key factor for compact devices. The requirement of heat exchanger like hair pin heat exchanger is proposed where the heat transfer rate is low. Suitable applications are refrigeration, air conditioning and space heating etc. Current study presents the investigation on hairpin exchanger using two different nanofluids Aluminium Oxide and Titanium Carbide mixed with base fluid individually at 0.6 and 0.7 percent volume fractions and analysed the performance using Computational Fluid Dynamics in the hair pin heat exchanger. Dispersion of nanoparticles in base fluid has emerged to enhance the thermal conductivity and rate of heat transfer. Computational fluid dynamic analysis is performed by applying the properties of nanofluids as input and thermal analysis was made on suitable material as Silver and Copper. Results indicate that Titanium carbide gives better coefficient of heat transfer with various nanofluids and copper is the suitable material used for fabricating heat exchanger for the flow of Titanium carbide fluid.
