Heat and Mass transfer of MHD Casson nano fluid flow through a porous Media past a Vertical plate with Chemical, Hall and Dufour effects

Abstract: In this article, we analyses unsteady MHD free convection heat transfer flow of viscous incompressible, electrically conducting Casson nano fluid across an infinite vertical permeable plate using diffusion thermo, Hall current, magnetic field, chemical reaction, and thermo diffusion. Copper (Cu), Silver (Ag), Ferric Oxide (Fe3O4) based nanofluid has been considered. Partial differential equations are transformed into ordinary differential equations using non-dimensional variables and then solved using the three term simple perturbation technique. The profiles of velocity, temperature, and concentration are all numerically determined, as are the skin fiction coefficient, Nusselt number, and Sherwood number. The Casson, magnetic, hall, porosity, and Prandtl numbers are only a few of the regulating factors that are carefully explored in connection to the flow and heat transfer properties of the nanofluids Cu, Ag, and Fe3O4. It is evident that raising the Dufour number causes Mass and Heat transmission to increase. Hall parameter effects increase the velocity profile. Key words: MHD, Casson nano fluid, Hall parameter, Dufour number, Perturbation method
