APPLICATION OF NANOFLUIDS IN SHELL AND TUBE HEAT EXCHANGER FOR HEAT TRANSFER ENHANCEMANT

Abstract

Heating and chemical reactors benefit substantially from the serpentine tube arrangement in a tubular structure. Small space and high heat transfer coefficients may be achieved using the serpentine tube-in-tube design. ' An investigation of the effects of nanofluids, such as Al2O3/water and CuO/water nanofluids, on heat transfer (HT) and efficiency of a serpentine tube heat exchanger is the goal of this study. Modeling in Creo and CFD simulations are carried out using ANSYS's FLUENT software, respectively. When nanofluids are used, shell and serpentine heat exchangers become more effective and efficient. There is no additional pressure loss over serpentine heat exchangers owing to the ultra-fine particles and tiny volume fractions of nanofluid coolant. For low velocities, nanofluids have a greater impact, but for high velocities, the flow rate will take precedence.
