“…The branch marked r-s corresponds to that given numerically by Terrill [3], Rosenhead [6] and Labropulu [15]; the last authors also give a small-Y Taylor expansion of this solution. However, this is not the only branch; indeed, we find that for a given value of γ in one particular range, there are at least three solutions to (4), as shown in Figures 1 and 2.…”

Multiple solutions are reported for the two-dimensional boundary layer flow of a viscous fluid near a permeable wall through which fluid is uniformly withdrawn. In the limit of large wall suction, three flows of similarity form are found: the first is the well-known monotonic solution of Terrill; the second exhibits flow reversal, with the streamlines being separated into three distinct cells; the third also exhibits flow reversal, but has multiple cells only when the fluid withdrawal speed is less than some threshold. The wall injection problem is also briefly studied, only Terrill's branch of solutions being found. Numerical and asymptotic solutions are presented and compared; the large-suction asymptotics of the third solution branch are found to be rather subtle.

“…Suction is applied to chemical processes to remove reactants. Blowing is used to add reactants, cool the surface, prevent corrosion or scaling and reduce the drag (Labropulu et al [10]). The effect of suction or injection at a stretched surface was considered by Erickson et al [11] and Fox et al [12] for uniform surface velocity and temperature.…”

“…Suction and injection have many applications from the engineering point of view such as thrust bearings and radial diffusers devices. During the chemical processing, suction and injection are extensively used to remove reactants and to add reactants, respectively, cooling the surfaces, scaling and reducing the drag (see Labropulu et al ). Massoudi and Ramazan studied the Falkner–Skan wedge flow and showed the effect of a non‐Newtonian second‐grade fluid on the wall shear and velocity profile for various suction/injection and wedge angle constraints.…”

In this study, the effects of viscous dissipation and internal heat generation/absorption on heat transfer viscous flow over a moving wedge in the presence of suction or injection with a convective boundary condition have been carried out numerically for various values of dimensionless parameters. With the help of similarity transformation, the momentum and energy equations are reduced to a set of coupled non‐linear ordinary differential equations. These equations are solved using the Runge–Kutta fourth‐order method with a shooting technique. The variation in the dimensionless temperature, velocity, heat transfer coefficient, and shear stress have been presented in tabular as well as in graphical form for a range of controlling parameters. It is shown that the dimensionless heat transfer rate is a strong function of viscous dissipation and convective parameters and heat transfer shows an enhanced behavior with the stretching parameter for both the favorable and unfavorable regimes. It is also shown that in the presence of a heat source, the dimensionless temperature and its gradients in thermal boundary layers are found to be high for a high value of the convection parameter. The comparison of present results with the available data shows a good agreement. © 2013 Wiley Periodicals, Inc.
