RESUMO

General boundary-layer equations governing steady, laminar, hydromag-netic flow and heat transfer over a non-isothermal permeable surface stretching with a power-law velocity with heat generation and suction/injection effects and in the presence of a non-uniform transverse magnetic field are developed. A similarity transformation is used to transform the governing partial differential equations into ordinary differential equations. Linearized flow solutions for the case of large magnetic numbers are derived. The dimension-less similar equations are then solved numerically by using a standard fully implicit, iterative, tri-diagonal finite-difference method. Favorable agreement between the finite-difference and the linearized flow solutions are obtained. In addition, comparisons with previously published work on various aspects of the problem are performed and found to be in excellent agreement. A parametric study of all the physical parameters involved in the problem is conducted. A representative set of numerical results is illustrated graphically and discussed.
