Abstract

This presentation highlights the heat transfer analysis in the mixed convective ferrofluid flow with variable thickness in numerous directions towards a rotating stretching disk. The magnetic field and porous medium are taken into consideration within the flow model, which has a plethora of packages in science, engineering and production zones. The equation of energy is scrutinized with the impact of nonlinear radiative terms. Convergent solution of the transformed system is simulated via the analytical procedure homotopy analysis method (HAM) with the help of MATHEMATICA software. It is noticed that for a higher amount of stretching parameter and disk thickness, the radial and axial velocities are enhanced. For higher values of radiation parameter, the Nusselt number increases, while it is decreased for larger value of power index law of disk thickness. Graphs of Nusselt number (heat transfer rate), Skin friction, temperature and velocity profiles are illustrated for the physical presentation of distinct fluid flow parameters.
