Summary: | The main aim of the present work is to highlight the significances of
periodic mixed convection flow and heat transfer characteristics along the
surface of magnetized cone by exerting magnetic field exact at the surface of
the cone. The numerical simulations of coupled non-dimensional equations are
computed in terms of velocity field, temperature and magnetic field
concentration and then used to examine the periodic components of skin
friction, ?w, heat transfer, qw, and current density, jw, for various
governing parameters. A nice periodic behavior of heat transfer qw is
concluded for each value of mixed convection parameter, ?, but maximum
periodicity is sketched at ? = 50. It is also computed that the lower value
of magnetic Prandtl number ? = 0.1 gets poor amplitude in current density but
highest amplitude is sketched for higher ? = 0.5. The behavior of heat and
fluid-flow in the pres?ence of aligned magnetic field is associated with the
phase angle and amplitude of oscillation. It is also noted that due to the
increase in magnetic force parameter, ?, there are wave like disturbances
generate within the fluid layers. These disturbances are basically
hydromagnetic waves which becomes more prominent as the strength of magnetic
force parameter is increased. |
