An analysis is performed to study the shear stress, the couple-stress and heat transfer characteristics of a laminar mixed convection boundary layer flow of a micropolar fluid past an isothermal permeable plate. The governing nonsimilar boundary layer equations are analyzed using the (i) series solution for small ξ, (ii) asymptotic solution for large ξ and (iii) primitive-variable formulation and the stream function formulation are being used for all ξ. The effects of the material parameters,

The agreement between the solutions obtained from the stream-function formulation and the primitive-variable formulation is found to be excellent.
