Effects of Mixed Convection on the Oscillatory Flow of a Couple Stress Fluid through a Vertical Plate with Variable Fluid Properties

Abstract

A numerical computation has been carriedout for the steady, mixed convective, incompressible, viscous, electrically conducting couple stress fluid through a vertical plate with variable fluid properties in a porous medium. A uniform magnetic field is applied in the transverse direction and parallel to the vertical plate of the physical model and governing equations are derived for it."Using a suitable similarity transformation, governed PDE's are transformed into a set of ODE's which are highly non-linear coupled equations. An advanced Shooting technique is adopted to compute the variations of velocity, temperature, concentration in terms of non-dimensional parameters. Also physical interpretation of non-dimensional parameters like couple stress parameter magnetic field Prandtl number Schmidt number thermal conductivity and solutal diffusivity parameters are examined through plots for both variable permeability and uniform permeability."From the numerical results, an excellent agreement has been observed for the present results, as well as comparison is made between the present and the earlier works for a particular case of the problem.

Effect of radiation and viscous dissipation using the Galerkin method over a vertical porous plate with variation in temperature

“…Reddy et al 16 analyze and determine the unsteady MHD, stream of a sticky, nonpressable, and electrically insulating moisture/fluid labeled Kuvshinski-fluid over an endless perpendicular porous sheet, of a homogeneous chemical reaction and radiation absorption, as well as a heat source/sink. Suresh Babu and colleagues [17][18][19] studied about variable fluid properties through a vertically heated plate embedded in a porous medium. Stream point stagnation of a nonpolar flow over an exponentially curved surface is investigated by Kempannagari et al 20 heat and mass transfer properties of an unsteady MHD boundary layer flow through, with pores over a stretched sheet in the presence of reaction kinematics applications, and thermophoresis, thermal, and irregular heat generation, are studied by Reddy et al 21 Kumar et al 22 investigated the heat consequences of a viscous radiating stream through a penetrable screen in the process of generated field of magnetic.…”
