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 ?, (ii) asymptotic solution for large ? and (iii)
primitive-variable formulation and the stream function formulation are being
used for all ?. The effects of the material parameters, such as, the vortex
viscosity parameter, K, and the transpiration parameter, s, on the shear
stress, the couple-stress and heat transfer have been investigated. The
agreement between the solutions obtained from the stream-function
formulation and the primitive-variable formulation is found to be excellent.
