چکیده
|
This paper investigates the unsteady magnetohydrodynamic (mhd) mixed convective fluid flow over a rotating sphere. an implicit finite difference scheme, together with quasi-linearization, is used to find non-similar solutions for the governing equations. the impact of variable physical properties and viscous dissipation are included. it is observed that the skin friction coefficient in the axial direction and the heat transfer coefficient are increasing with an increase in mhd, mixed convection and rotation parameters and with time, whereas the effect is just the opposite for the skin friction coefficient in the rotational direction. the non-uniform slot suction(injection) and the slot movement influence the point of vanishing skin friction to move in the axial direction downstream (upstream).
