“…Ishak et al [7] studied the steady laminar MHD boundary layer flow along a wedge immersed in an incompressible micropolar fluid in the presence of a variable magnetic field. Rahman and his coworkers have studied and reported results on micropolar fluids for various flow and thermal conditions in different geometries [8][9][10][11][12][13][14][15][16]. Elbashbeshy et al [17] studied the effect of magnetic field on boundary layer flow over an unsteady stretching surface in a micropolar fluid.…”

In this paper we analyze unsteady two dimensional hydromagnetic forced convective heat transfer flow of a viscous incompressible micropolar fluid along a permeable wedge with convective surface boundary condition. The potential flow velocity has been taken as a function of the distance x and time t. The governing time dependent non-linear partial differential equations have been reduced to a set of non-linear ordinary differential equations by introducing a new class of similarity transformations. Comparisons with previously published work are performed, and the results are found to be in excellent agreement. The resulting local similarity equations for unsteady flow have been solved numerically by applying NachtsheimSwigert shooting iteration technique along with sixth order Runge-Kutta integration scheme.Numerical results in the form of nondimensional velocity, microrotation and temperature profiles are presented graphically and discussed for different material parameters entering into the analysis. The effects of the pertinent parameters on the local skin-friction coefficient, plate couplestress and the rate of heat transfer are also displayed in tabulated form and discussed them from the physical point of view. The obtained numerical results show that the rate of heat transfer increases with the increase of the unsteadiness parameter and decreases with the increase of the surface convection parameter.

“…However, it is well known [23][24][25][26][27][28][29][30] that these physical properties may change with temperature, especially fluid viscosity and thermal conductivity. For lubricating fluids, heat generated by internal friction and the corresponding rise in the temperature affects the physical properties of the fluid and so the properties of the fluid are no longer assumed to be constant.…”

The influence of partial slip, thermal radiation and temperature dependent fluid properties on the hydromagnetic fluid flow and heat transfer over a flat plate with convective surface heat flux at the boundary and nonuniform heat source/sink is studied. The transverse magnetic field is assumed as a function of the distance from the origin. Also it is assumed that the fluid viscosity and the thermal conductivity vary as an inverse function and linear function of temperature respectively. Using the similarity transformation, the governing system of nonlinear partial differential equations are transformed into similarity non-linear ordinary differential equations and are solved numerically using symbolic software MATHEMATICA 7.0. The numerical values obtained within the boundary layer for the dimensionless velocity, temperature, skin friction coefficient and the Nusselt number are presented through graphs and tables for several sets of values of the parameters. The effects of various physical parameters on the flow and heat transfer characteristics are discussed from the physical point of view.

The present paper focuses on the analysis of thermophoretic hydromagnetic slip flow over a permeable flat plate with convective surface heat flux at the boundary and temperature dependent fluid properties in the presence of non-uniform heat source/sink. The transverse magnetic field is assumed to be a function of the distance from the origin. Also it is assumed that the liquid viscosity and the thermal conductivity vary as an inverse function and a linear function of temperature, respectively. The shooting method is employed to yield the numerical solutions for the model. Results show that the thermal boundary layer thickness reduces with increase of surface convection parameter whereas reverse effect occurs for viscosity parameter. It is also observed that the thermophoretic parameter decreases the concentration distribution across the boundary layer. ª 2014 Production and hosting by Elsevier B.V. on behalf of Faculty of Engineering, Alexandria University.
