Description
Summary:Heat transport phenomenon in partially ionized non-Newtonian liquid, the Eyring-Powell, in the presence of magnetic field is modeled through mathematical equations of governing laws. The complex coupled set of PDE's are set into dimensionless form and solved by finite element method. Mesh free and convergent solutions are computed. Parametric analysis is done in order to investigate the influence of emerging parameters on the flow and heat transport fluid regime. Hall and ion slip currents have vital role in decreasing the heat dissipation in Eyring-Powell liquid (composed of charges and ions). The wall velocity and wall temperature gradient are significantly influenced by Eyring-Powell rheology and ion and charged in fluid exposed to the magnetic field. The velocity of fluid slows but temperature increases when intensity of magnetic field is increased.
