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.
