MHD Flow of a Micropolar Fluid past a Stretched Permeable Surface with Heat Generation or Absorption

This work considers steady, laminar, MHD flow of a micropolar fluid past a stretched semi-infinite, vertical and permeable surface in the presence of temperature- dependent heat generation or absorption, magnetic field and thermal radiation effects. A set of similarity parameters is employed to convert the governing partial differential equations into ordinary differential equations. The obtai ned self-similar equations are solved numerically by an efficient implicit, iterative, fini te-difference method. The obtained results are checked against previously published work for special cases of the problem in order to access the accuarcy of the numerical method and found to be in excellent agreement. A parametric study illustrating the i nfluence of the various physical parameters on the skin friction coefficient, microrotaion c oefficient or wall couple stress as well as the wall heat transfer coefficient or Nusselt numbe r is conducted. The obtained results are presented graphically and in tabular form and the physical aspects of the problem are discussed.
