DYNAMICS OF FLOW AND HEAT TRANSFER MECHANISM OF HYDROMAGNETICMAXWELL FLUID OVER A SPINNING DISK WITH MARANGONI EFFECTS

Abstract

Investigating the flow of non-Newtonian fluids influenced by a magnetic field is important to improve current thermal systems through different technologies. Typical of these applications can be found in polymer processing devices, rotating equipment, microfluidic devices, and cooling mechanisms. The goal of this paper is to investigate the dynamics of flows and heat-mass transfer mechanism of hydromagnetic Maxwell fluids over a rotating disk featuring Marangoni convection, thermal radiation, and bioconvection effects. The initially developed model equations are restructured into ordinary differential equations and solved numerically by shooting and Runge-Kutta Felhberg method. The findings which are reported through various graphs indicate that there is a decline in the velocity field with increasing fluid material parameter and porous medium resistance, whereas the temperature field intensifies in the with magnification of thermophoresis, thermal radiation, and Brownian motion terms. Furthermore, the viscoelastic nature of the Maxwell nanofluid enhances resistance to deformation, thereby reducing momentum transport and providing a mechanism for regulating fluid elasticity and improving heat transfer along the disk surface.
