COUPLED HEAT AND MASS TRANSFER IN TRANSIENT MAGNETOHYDRODYNAMIC NANOFLUID FLOW PAST A VERTICAL PLATE: EFFECTS OF BUOYANCY AND TEMPERATURE VARIATION

The current research offers a detailed assessment of heat and mass transfer processes in magnetohydrodynamic (MHD) systems, emphasizing real-world applications where varying temperature conditions and consistent concentration distributions exist. An external magnetic field is applied, and the plate encounters a variable thermal state alongside fixed solutal level boundary conditions. At the same time, the nanofluid consists of copper nanoparticles suspended in a water-based medium. The governing equations related to unsteady interface dynamics, concerning momentum, heat, and mass transfer, are solved using the Laplace Transform technique. The investigation highlights the importance of specific critical parameters, such as nanoparticle size, magnetic induction, thermal Grashof number, and variable surface temperature, on the distributions of velocity, temperature, and concentration. The findings indicate that variations in temperature conditions have a substantial impact on the rates of heat and mass transfer in MHD systems, with optimal performance attained through meticulous regulation of magnetic field factors and thermal boundary conditions.
