چکیده

Hall effects on combined free and forced convective flow of a viscous-elastic incompressible electrically conducting fluid between the horizontal perfectly conducting plates under the action of a uniform transverse magnetic field applied parallel to the axis of rotation is studied. Exact solution of the governing equation is obtained in closed form. It is observed that Hall current exerts stabilizing influence on the primary flow at the upper plate due to shear stress while at the lower plate Grashof number causes separation on the secondary flow. The rate of heat transfer at both the plates are derived. It is found that the Hall current and rotation exert reverse flow of heat at the upper plate when the numerical value is equal to two as the Grashof number is being referred. Mass transfer is analysed by solving the constitutive equations for concentration.
