CONVECTIVE MHD FLOW PAST AN IMPULSIVELY STARTED VERTICAL PLATE WITH PERIODIC TEMPERATURE AND CONCENTRATION IN PRESENCE OF THERMAL RADIATION AND CHEMICAL REACTION

This study investigated a two-dimensional unsteady MHD-free convection of a viscous, incompressible fluid past through an impulsively started vertical plate in the presence of thermal radiation and chemical reactions. The Laplace transform method is used to solve the second-order partial differential equations. The effect of various related parameters on the velocity field, temperature field, and concentration field are demonstrated graphically. The effects of the Nusselt number, Sherwood number, and skin friction for the influence of different parameters are also graphically visualized. It is noticed that the increment in Soret number hikes the fluid velocity and concentration. Also, the Hartmann number reduces the velocity of the fluid. Present work is important in various industrial and engineering sectors, such as chemical and power industries, glass production, steel rolling etc.

Transient Mixed Convection Boundary Layer Flow of an Incompressible Fluid Past a Wedge in Presence of Magnetic Field

In this paper, an analysis is performed to explorethe transient, laminar two-dimensional, mixed convection boundary layer flow of a viscous and incompressible fluid past a vertical wedge taking into account the effect of magnetic field. With appropriate transformations the boundary layer equations are reduced to a local nonsimilarity equations and the solutions are obtained employing three distinct methods, namely, (i) perturbation method for small time; (ii) asymptotic solution method for large time; (iii) straight forward finite difference method for any time. The agreement between the solutions obtained from prescribed methods is found to be excellent. In this study the evaluation of skin-friction coefficient and the local Nusselt number with the effects of different governing parameters such as different time, τ, the exponent, m (= 0.4, 0.5, 1.0), mixed convection parameter, λ (= 0.0, 0.2, 0.4) and magnetic field parameter, M (=0.0, 1.0) for fluids having Prandtl number, Pr= 0.72, 1.0 and 7.0have been discussed. It is observed that both the local skin friction and local Nusseltnumber decreases due to an increase in the value of M. It is also found that an increase in the value of Prandtl number, Pr, leads to a decrease in the value of local skin friction coefficient and the value of local Nusselt number coefficient increases with the increasing values of Prandtl number.

Influence of thermal radiation, viscous dissipation and Hall current on MHD convection flow over a stretched vertical flat plate

A boundary layer analysis has been presented to study the effects of thermal radiation, viscous dissipation, and Hall current effects on the hydromagnetic convection flow of an electrically conducting, viscous, incompressible fluid past over a stretching vertical flat plate. The governing partial differential equations are non-dimensionalized and transformed into a system of nonlinear ordinary differential similarity equations, in a single independent variable. The resulting coupled nonlinear equations are solved under appropriate transformed boundary conditions using the Runge–Kutta fourth-order method along with the shooting method. The effects of the radiation parameter, magnetic parameter, Hall parameter, viscous dissipation parameter and the buoyancy parameter on the velocity profiles, the cross flow velocity profiles and the temperature profiles are presented graphically and discussed.

Hydromagnetic flow near an accelerated plate with suction

The two-dimensional unsteady flow of a conducting viscous incompressible fluid past, an infinite flat plate with uniform suction, is considered in the presence of a uniform magnetic field. For a constant time, it is shown that for a given Hartmann numbera, as the cross Reynolds number β (corresponding to the suction velocity of the plate) increases, the velocity at any point of the fluid decreases and the skin friction at the plate increases. The results also hold good for a given β, asa increases if the magnetic lines of force are fixed relative to the fluid and are just opposite for the magnetic lines of force fixed relative to the plate.
