“…For fixed value of c , corresponding to the stretching of the surface, increase in a in relation to c (such that /1 ac  ) implies increase in straining motion near the stagnation region. Due to this reason the acceleration of the external stream is increased and this leads to thinning of the boundary layer (Layek et al [30]). On the other hand when /1 ac  , the flow has an inverted boundary layer structure.…”

This article investigates the influence of variable heat flux on the problem of steady two dimensional MHD flow and heat transfer of an electrically conducting fluid along a semi-infinite vertical plate taking into account the effect of viscous dissipation. The governing equations are converted into a system of nonlinear ordinary differential equations via a similarity variable. The resulting system of equations is then solved numerically by using Natchsheim Swigert shooting iteration technique together with sixth order RungeKutta integration scheme. Boundary layer velocity and temperature profiles are determined numerically for various values of the ratio of free stream velocity and stretching velocity, the magnetic field parameter, suction/blowing parameter, Brinkman number. Regardless of the flow conditions, the flow velocity and temperature is found significantly affected by the flow parameters.

“…On the other hand, Chiam [3] reported the analytical and numerical solutions of the stagnation-point flow over a flat stretching sheet with variable thermal conductivity. Since then, many researchers, such as Mahapatra and Gupta [4,5], Ishak et al [6,7], Layek et al [8], Nadeem et al [9], Bachok et al [10], Bhattacharyya and Layek [11], and Lok et al [12] have investigated the behavior of stagnation-point flow with different aspects and conditions such as considering magnetic field effect, homogeneous-heterogeneous reactions effect, thermal radiation effect, suction/blowing, and micropolar fluid.…”

Abstract:The effects of partial slip on stagnation-point flow and heat transfer due to a stretching vertical sheet is investigated. Using a similarity transformation, the governing partial differential equations are reduced into a system of nonlinear ordinary differential equations. The resulting equations are solved numerically using a shooting method. The effect of slip and buoyancy parameters on the velocity, temperature, skin friction coefficient and the local Nusselt number are graphically presented and discussed. It is found that dual solutions exist in a certain range of slip and buoyancy parameters. The skin friction coefficient decreases while the Nusselt number increases as the slip parameter increases.

“…Their work was then extended by Devi et al [5] to the unsteady case and by Lok et al [15] to a vertical surface immersed in a micropolar fluid. Layek et al [14] analyzed the flow and heat transfer boundary layer stagnation-point flow of an incompressible and viscous fluid towards a heated porous stretching sheet embedded in porous media subject to suction/blowing with internal heat generation or absorption. Recently, Adrian [1] studied heat and mass transfer by natural convection at a stagnation-point in a porous medium by considering Soret and Dufour effects.…”

This paper investigates the hydromagnetic stagnation point flow of an incompressible viscous electrically conducting fluid towards a stretching sheet in the presence of radiation and viscous dissipation. The Newton-Raphson shooting method along with the fourth-order Runge-Kutta integration algorithm has been employed to tackle the third order, nonlinear boundary layer problem governing the flow. Numerical results for dimensionless local skin friction coefficient and the local Nusselt numbers are presented in tables while graphical results are presented for velocity and temperature profiles for various values of the controlling parameters. The results show that the heat transfer of a hydromagnetic fluid over a porous stretching surface subject to radiation and viscous dissipation can be controlled and a final product with desired characteristics can be achieved.
