Discussion: “Magnetohydrodynamic Flow Past a Vertical Plate With Radiative Heat Transfer” (Shateyi, S., Sibanda, P., and Motsa, S. S., 2007, ASME J. Heat Transfer, 129, pp. 1708–1713)

Abstract

In the above paper (Shateyi et al. (1)) the authors treat the boundary layer flow along a vertical semi-infinite, isothermal plate of an electrically conducting fluid. The flow is influenced by a horizontal magnetic field taking into account the Hall effects. In the energy equation the radiation has been included. The boundary layer equations are transformed from the x, y coordinates into ξ, η and subsequently are solved numerically using the Blottner method. However, there are some significant errors in the above paper which are presented below:
