“…Choudhury and Das [28] have studied viscoelastic mhd free convective flow through porous media in presence of radiation and chemical reaction with heat and mass transfer. Choudhury and Dey [29], Choudhury and Mahanta [30], Choudhury and Das [31], Sandeep et al [32], Subhash et al [33], and Suneetha et al [34] have analyzed some problems of physical interest in this field. Cogley et al [35] have investigated the differential approximation for relative heat transfer in a grey gas near equilibrium.…”

An analysis of the steady free convective flow and heat transfer of a visco-elastic fluid confined between a long vertical wavy wall and a uniformly moving parallel flat wall has been presented. The x axis is taken along the length of the walls while the walls are given by y=εcos(Kx) and y=d. A uniform magnetic field is assumed to be applied normal to the flat wall. The equations governing the fluid flow and heat transfer have been solved by perturbation technique subject to the relevant boundary conditions. It is assumed that the solution consists of two parts, a mean part and a perturbed part. The long wave approximation has been used to obtain the solution of the perturbed part and to solve the mean part the well known approximation used by Ostrach [1] has been utilized. The perturbed part of the solution is the contribution from the waviness of the wall. Expressions for the zerothorder and first order velocity, temperature, non-dimensional skin friction at the walls and pressure drop are obtained. The first order velocity, pressure drop, and skin friction coefficient have been presented graphically to observe the visco-elastic effects in combination of other flow parameters involved in the solution.

The magnetohydrodynamic (MHD) convective flow of a viscoelastic, incompressible and electrically conducting fluid through a porous medium filled in a vertical channel is analyzed. The channel plate at * = − is subjected to a slip-flow condition and the other at * = + to a no-slip condition. The temperature of the plate at * = + with no-slip condition is assumed to be varying both in space and time. The temperature difference of the walls of the channel is assumed high enough to induce heat transfer due to radiation. A magnetic field of uniform strength is applied perpendicular to the planes of the channel walls. The magnetic Reynolds number is assumed very small so that the induced magnetic field is neglected. It is also assumed that the conducting fluid is optically-thin gray gas, absorbing/ emitting radiation and non-scattering. Exact analytical solutions of the non-linear partial differential equations governing the flow problem are obtained. The velocity field, the temperature field, the amplitude and the phase angle of the skin friction and the heat transfer coefficient are shown graphically and their dependence on the various flow parameters is discussed in detail.

In this study, the unsteady magnetohydrodynamic (MHD) flow and heat trasnfer of a dusty, viscoelastic, incompressible and electrically conducting fluid in an inclined channel in the presence of thermal radiation and heat source has been investigated. The non-dimensional equations governing the flow are solved by parametric perturbation technique under the prescribed boundary conditions. The solutions of the equations governing the flow are obtained for fluid velocity, dust particle velocity, temperature and dust particle temperature profile.The results have been expressed graphically and in tabular form to observe the effects of different flow parameters. The effect of the various parameters entering in the governing equations on the flow are evaluated numerically and discussed with the help of graphs and tables.
