“…Free convection flow along a vertical plate with arbitrary blowing and wall temperature has also been investigated by Vedhanayagam et al [20]. The free convection flow over a horizontal plate was investigated by Lin and Wu [21], who considered temperature and transpiration rates, which both followed power-law variations. Hossain et al [8,22] investigated the natural convection flow from a vertical permeable flat plate with variable surface temperature, considering temperature and transpiration rates which both followed power-law variations.…”

The effect of the Hall current on the magnetohydrodynamic (MHD) natural convection flow from a vertical permeable flat plate with a uniform heat flux is analyzed in the presence of a transverse magnetic field. It is assumed that the induced magnetic field is negligible compared with the imposed magnetic field. The boundary layer equations are reduced to a suitable form by employing the free variable formulation (FVF) and the stream function formulation (SFF). The parabolic equations obtained from FVF are numerically integrated with the help of a straightforward finite difference method. Moreover, the nonsimilar system of equations obtained from SFF is solved by using a local nonsimilarity method, for the whole range of the local transpiration parameter ζ. Consideration is also given to the regions where the local transpiration parameter ζ is small or large enough. However, in these particular regions, solutions are acquired with the aid of a regular perturbation method. The effects of the magnetic field M and the Hall parameter m on the local skin friction coefficient and the local Nusselt number coefficient are graphically shown for smaller values of the Prandtl number P r (= 0.005, 0.01, 0.05). Furthermore, the velocity and temperature profiles are also drawn from various values of the local transpiration parameter ζ.

“…A transformation of the equations for general blowing and wall temperature variations has been given by Vedhanayagam et al [6]. The case of a heated isothermal horizontal surface with transpiration has been discussed in some detail first by Clarke and Riley [7,8], and more recently by Lin and Yu [9].…”

The effects that blowing and suction have on the free convection boundary layer on a vertical surface with a given surface heat flux are considered. Similarity equations are derived first, their solution being dependent on the wall flux exponent n and a dimensionless transpiration parameter y, (as well as on the Prandtl number). The range of existence of solutions is considered, with it being shown that solutions exist only for n > -1 for blowing, whereas they exist for all n > n o for suction, where n o < -1 and depends on y. The solutions for strong suction and blowing are derived. In the latter case the asymptotic structure is found to be different for n in the three ranges -1 < n < -, -< n < , n > -. Results are then obtained for the non-similarity problem of constant heat flux with a constant transpiration velocity. Solutions valid for large distances from the leading edge for both suction and blowing are derived.
