Hydromagnetic Three Dimensional Couette Flow and Heat Transfer

Abstract

and tables. It is observed that the magnetic parameter (M) has a retarding effect on the main velocity (u) and an accelerating effect on the cross velocity (w 1 ) of the flow field. The suction parameter (R e ) has a retarding effect on the main velocity as well as on the temperature field. The Prandtl number (P r ) reduces the temperature of the flow field and increases the rate of heat transfer at the wall (N u ). The effect of suction parameter is to reduce the x-component of skin friction and to enhance the magnitude of zcomponent of the skin friction at the wall. The problem is very much significant in view of its several engineering, geophysical and industrial applications.

Effect of constant suction and injection on MHD three dimensional couette flow and heat transfer through a porous medium

“…Higher this value, the more prominent is the reduction in velocity. Our results closely match with those obtained in case of Das et al (2008).…”

“…Both suction / injection parameter and the Prandtl number have substantial effect on the temperature field. The temperature profiles agree with the results of Das et al (2008). In Fig.…”

“…For solution, we shall first consider three Equations (28), (30) and (31) being independent of the main flow component u 1 and the temperature field T 1 . Following Das et al (2008), we assume v 1, w 1 and p 1 of the following form:…”

“…Jain et al (2006) investigated the three dimensional couette flow with transpiration cooling through a porous medium in the slip flow regime. Recently, Das et al (2008) analyzed the three dimensional couette flow and heat transfer in presence of a transverse magnetic field.…”

Effect of heat source and chemical reaction on MHD flow past a vertical plate with variable temperature

“…Prasad et al (2007) have discussed radiation and mass transfer effects on two-dimensional flow past an impulsively started infinite vertical plate. Das et al (2008) analyze the three dimensional coquette flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel porous flat plates in presence of a transverse magnetic field. Seth and Ansari (2010) have studied the MHD natural convection flow past an impulsively moving vertical plate with ramped wall temperature in the presence of thermal diffusion with heat absorption.…”
