Radiation effects on the MHD flow near the stagnation point of a stretching sheet

Abstract

The radiation effects using the Rosseland approximation on the flow of an incompressible viscous electrically conducting fluid over a stretching sheet near the stagnation point in the presence of uniform transverse magnetic field is studied. The governing equations transform to ordinary differential equation by using suitable similarity transformation and then by a perturbation technique the numerical results for temperature distribution were obtained and discussed graphically.

Radiation effects on the MHD flow near the stagnation point of a stretching sheet: revisited

“…u w (x) = bx and u e (x) = ax, respectively, where a and b are constants. Different from Jat and Chaudhary [1], we assume that the surface temperature varies with the distance from the stagnation point in the form T w = T ∞ + cx 2 , where T ∞ is the ambient temperature, and c is a constant. Under these assumptions, the boundary layer equations are (cf.…”

“…Under these assumptions, the boundary layer equations are (cf. Jat and Chaudhary [1], Bataller [3] and Makinde and Aziz [4]) …”

“…In addition, it should be mentioned that Eqs. (6) and (7) were wrongly derived in the paper by Jat and Chaudhary [1]. The physical quantities of interest are the skin friction coefficient C f and the local Nusselt number Nu x which are proportional to f (0) and −θ (0), respectively.…”

“…In a recent paper, Jat and Chaudhary [1] extended the problem considered by Pop et al [2], by including the magnetic field terms in the momentum and energy equations. Unfortunately, these equations were not correctly derived, and the associated boundary condition far away from the solid surface is not satisfied.…”

Partial slip and thermal radiation effects on hydromagnetic flow over an exponentially stretching surface with suction or blowing

“…The radiative heat flux is described by using the Rosseland approximations in the energy equations. The thermal radiation effects on the flow with and without a magnetic field with several cases were presented by Bestman and Adjepong [32], Naroua et al [33], Ouaf [34], Makinde and Ogulu [35], Pal and Mondal [36], and Jat and Chaudhary [37]. Most recently, Elbashbeshy and Emam [38], Khan et al [39], Chaudhary et al [40], and Sandeep et al [41] analyzed the radiation effects over viscous incompressible and MHD flow.…”
