“…Figure 1 gives the variation of f along with the distance from the plate. The variation of 1 A , the parameter which is associated with the viscosity function of the temperature produce a substantial change in a single valued function f of  . It is observed that the values of f increases sharply in magnitude as the values of 1 A increases.…”

The boundary layer flow of a steady incompressible and visco-elastic fluid with short memory (obeying Walters' B fluid model) passing over a hot vertical porous plate has been investigated in the presence of transverse magnetic field. The momentum and energy equations are reduced to couple non-linear partial differential equations along with the boundary conditions by using a suitable similarity transformation. These partial differential equations are transformed to a system of coupled non-linear ordinary differential equations by employing a perturbation technique. The system is solved by developing a suitable numerical procedure such as implicit finite difference scheme along with Newton's linearization method. The computational results for the flow quantities have presented graphically for the effects of thermal radiation, viscous dissipation, heat generation/absorption, visco-elasticity, Hartmann number and the permeability parameter. Results demonstrated that Prandtl number has more pronouncing effect on the temperature distribution rather than the viscosity parameter as well as the thermal radiation parameter. Further the velocity gradient changes significantly due to the presence of temperature dependent variable viscosity.

“…Considering the application in underground water resource and seepage of water under dam, Raptis et al [1] examined the free convection flow through a vertical porous media. In the other context Raptis et al [2,3] studied the similar problem by introducing mass transfer, constant suction and constant heat flux.…”

“…The flow through porous medium is very important particularly in the fields of agricultural engineering and technology for irrigation processes, especially in petroleum industry to study petroleum extraction process and transport, also in chemical engineering and technology for filtration and purification processes. A succession of explorations made by Raptis et al 1,2,3 into the study of two-dimensional flow through porous medium past an infinite vertical wall. Many authors [4][5][6][7][8][9] discussed an oscillatory three-dimensional flow through a porous medium.…”

In this paper, we consider hydromagnetic convective flow of an electrically conducting visco-elastic fluid through a rotating porous channel taking hall current into account. The governing equations are framed using Brinkman model. The exact solutions of the velocity and the temperature distributions are evaluated analytically using Laplace transform technique and which consist of the both steady and transient states. Thought is centered on the physical character of the solutions, and the construction of the various kinds of boundary layers outward appearance on the plates. The ultimate steady state velocity and temperature distributions are numerically discussed for various values of the flow parameters. The shear stresses and the Nusselt number are tabulated and discussed.

“…Afifi [6] studied the aspects of a magneto-fluid with suspended particles. The fluid motion through a porous medium has been studied by many authors [7][8][9][10][11][12][13][14][15]. Tripathi [16,17] studied the influence of heat transfer in swallowing of food bolus (water) through the oesophagus and heat flow through porous finite channel.…”
