Abstract

This research investigates the enhanced heat transfer capabilities of Graphene Oxide (GO) nanofluid combined with a helical coil configuration in shell and tube heat exchangers. Computational Fluid Dynamics (CFD) simulations using ANSYS Fluent 2022 software were conducted to analyze heat transfer performance under varying flow rates of hot and cold fluids. The study compares heat exchangers equipped with GO nanofluid and a helical coil to traditional water-water configurations, focusing on parameters such as heat flux, convective heat transfer coefficients, and temperature profiles. Results indicate that GO nanofluid, when used with a helical coil, consistently achieves higher heat flux values, optimizing thermal efficiency across different flow conditions. Convective heat transfer coefficients for the cold fluid remain stable with GO and the helical coil, highlighting its efficacy in maintaining efficient heat exchange. Temperature profiles reveal significant improvements in thermal regulation, with GO contributing to temperature differentials conducive to enhanced heat transfer rates. These findings underscore the potential of advanced nanofluid technologies in improving heat exchange efficiency in industrial applications. Future research could explore further optimizations and practical implementations of GO nanofluid in diverse thermal management systems.
