Abstract
A finite element numerical simulation is undertaken to explore the aspects of an angled magnetic field and thermo-diffusion on the unsteady mixed convection flow of hydro- magnetic chemically reacting and dissipating Casson fluid with thermal radiation. The fluid streams across an oscillating tilted plate ingrained in a porous medium, with time-dependent variations in temperature and concentration. The coupled dimensionless partial differential equations guiding the flow along their associated initial and boundary conditions are solved by utilizing an efficient finite element method. The key parameters affecting the fluid velocity, temperature, and species concentration are comprehensively interpreted through graphical representations while the skin friction, heat transfer, and mass transfer rates are outlined via tables. The ultimate results of the study portrayed that the plate inclination angle, Casson parameter, and applied magnetic strengths are perceived to impede the fluid velocity and the local skin friction whereas the porosity parameter displays a reverse effect. The thermo-diffusion effect amplifies the fluid velocity and species concentration. The heat source and Eckert number boost the fluid velocity and temperature. Moreover, there is an upsurge in the Nusselt number with radiation parameters and time. The Sherwood number increases with the chemical reaction but it decays with the thermo-diffusion parameter. A comparative analysis between the current findings and existing research works in the literature demonstrates the results’ precision and exactitude.
