Description
Summary:This study discusses double diffusion of nanoparticles and solute presuming the impacts of diffusion thermo and thermal diffusion numerically by adapting finite element method. Complex models are solved in order to examine the role of Soret and Dufour parameters on the double diffusion mechanism. The imposition of external non-uniform magnetic field makes the fluid to be capable of controlling the flow field. Consequently, such flow situations may be used in control-based applications in the field of hydro-magnetic power generation and electromagnetic metal casting phenomenon. The Brownian and thermophoresis effects have shown significant impact on double diffusion phenomenon in Weissenberg rheological fluid regime. Further, any flowing material is imperiled to magnetic field and ostensible viscous effects enhance. It can be concluded that unsteadiness effects enhance the molecular movement which results in the increment in the velocity of fluid.
