“…After these works, various aspects of stagnation-point flow and heat transfer toward a stretching sheet were investigated by Chiam [7], Maha patra and Gupta [8], Layek et al [9], and many others. Further more, the behavior of MHD stagnation-point flow under different physical aspects were discussed by Mahapatra and Gupta [10], Ishak et al [11], Mahapatra et al [12] Nadeem et al [13], and many others.…”

In this paper, the problem of steady two-dimensional magnetohy drodynamic (MHD) stagnation-point flow and heat transfer of an incompressible viscous fluid over a stretching!shrinking sheet is investigated in the presence of velocity and thermal slips. With the help of similarity transformations, the governing Navier-Stokes and the energy equations are reduced to ordinary differential equations, which are then solved numerically using a shooting technique. Interesting solution behavior is observed for the similarity equations with multiple solution branches for certain parameter domain. Fluid velocity increases due to the increasing value of the velocity slip pa rameter resulting in a decrease in the temperature field. Tempera ture at a point increases with increase in the thermal slip parameter. The effects of the slips, stretching!shrinking, and the magnetic parameters on the skin friction or the wall shear stress, heat flux from the swface of the sheet, velocity, and temperature profiles are computed and discussed.

“…Eldahab and Ghonaim [19] considered radiation effect on heat transfer characteristics of a micropolar fluid past unmoving horizontal plate through a porous medium. The unsteady MHD boundary layer flow of a micropolar fluid near the stagnation point of a two-dimensional plane surface through a porous medium has been examined by Nadeem et al [20]. In the present work, we consider the flow and heat transfer of a micropolar fluid towards a permeable stretching/shrinking surface in a porous medium with suction To the best of our knowledge, this problem has not been considered before, so that the results are new.…”

“…Furthermore, Ishak et al [9] studied MHD mixed convection flow on a vertical permeable surface. Similarly, the hydromagnetics flow towards a stretching sheet with various aspects, such as types of fluids, magnetic effect, stagnation geometry, and temperature effect are studied by investigators [10][11][12][13][14][15][16][17][18][19].…”

The boundary-layer flow and heat transfer over a non-isothermal stretching sheet in a nanofluid with the effect of magnetic field and thermal radiation have been investigated. The transport equations used for the analysis include the effect of Brownian motion and thermophoresis. The solution for the temperature and nanoparticle concentration depends on six parameters, viz., thermal radiation parameter R, Prandtl number Pr, Lewis number Le, Brownian motion Nb, and the thermophoresis parameter Nt. Similarity transformation is used to convert the governing nonlinear boundary-layer equations into coupled higher order nonlinear ordinary differential equations. These equations were numerically solved using a fourth-order Runge-Kutta method with shooting technique. The analysis has been carried out for tv.'o different cases, namely prescribed suiface temperature (PST) and prescribed heat flux (PHF) to see the ejfects of governing parameters for various physical conditions. Numerical results are obtained for distribution of velocity, temperature and concentration, for both cases i.e., prescribed surface temperature and prescribed heat flux, as well as local Nusselt number and Sherwood number. The results indicate that the local Nusselt number decreases with an increase in both Brownian motion parameter Nb and thermophoresis parameter Nt. However, the local Sherwood number increases with an increase in both thermophoresis parameter Nt and Lewis number Le. Besides, it is found that the surface temperature increases with an increase in the Lewis number Le for prescribed heat flux case. A comparison with the previous studies available in the literature has been done and we found an excellent agreement with it.
