Enhanced Heat Transfer in Vertical Channels via Non-Darcy Flow with SWCNTs and MWCNTs: Arrhenius Activation and Viscosity Variations

The effective management of heat transfer processes is critical in various engineering applications, including thermal management systems and advanced cooling technology. Nanofluids, with their distinct thermal properties, present significant opportunities for improving heat transmission. The Arrhenius activation model is used to investigate the thermal behaviour of nanofluids. This study investigates the joint effect of Arrhenius activation on the non-darcy hydromagnetic convective heat and mass transfer of a nanofluid in a vertical channel using both SWCNT and MWCNT. The Runge-Kutta fourth-order shooting technique was used to analyze the coupled nonlinear equations governing flow heat transfer. Graphical research has been conducted to investigate the impact of different activation energies, viscosity levels, heat sources, and chemical reactions on flow characteristics. A numerical analysis is performed to determine the skin friction, the rate of heat transfer, and the mass transfer for various parametric variables.
