Heat Transfer in Hydromagnetic Flow over an Unsteady Stretching Permeable Sheet

Unsteady laminar boundary layer flow of viscous incompressible electrically conducting fluid along a continuous stretched permeable surface with the magnetic field effect is investigated. The defining characteristics of unsteady laminar boundary layer flow are governed a more than one independent variables, stretching velocity and surface temperature of the field. Governing equations are obtained for influencing parameters and transformed into ordinary differential equations by taking convenient similarity variables. Runge-Kutta fourth order method in corporation by the shooting technique is introduced to carry out numerical computations of the investigation. Velocity and temperature profiles are computed and represented graphically for the influences of suction/injection parameter, unsteadiness parameter, magnetic parameter and Prandtl number, while numerical solutions of local skin friction coefficient and local Nusselt number are discussed through tables. For non-magnetic condition, results are found in concordance with earlier research work.

Heat Transfer in Hydromagnetic Couette Flow of Compressible Newtonian Fluid

Heat transfer in the hydromagnetic flow of a compressible Newtonian fluid, between a moving impermeable plate and a stationary naturally permeable bed, is investigated in the presence of a transverse magnetic field. The effects of the permeability and magnetic field on the velocity and temperature field are commented on, taking the viscous heating and Ohmic dissipation into consideration.
