FLOW OF A HEATED FERROFLUID OVER A STRETCHING SHEET IN THE PRESENCE OF A MAGNETIC DIPOLE

The flow of a viscous ferrofluid over a stretching sheet in the presen ce of a magnetic dipole is considered. The fluid momentum and thermal energy equations are formulated as a five-parameter problem, and the i nfluence of the magneto-thermomechanical coupling is explored numerica lly. It is concluded that the primary effect of the magnetic field is to decelerate the fluid motion as compared to the hydrodynamic case, t hereby increasing the skin friction and reducing the heat transfer rat e at the sheet.
