Two dimensional flow of a micropolar fluid in a porous channel is investigated. The flow is driven by suction or injection at the channel walls, and the micropolar model due to Eringen is used to describe the working fluid. An extension of Berman's similarity transform is used to reduce the governing equations to a set of non-linear coupled ordinary differential equations. The latter are solved for large mass transfer via a perturbation analysis where the inverse of the crossflow Reynolds number is used as the perturbing parameter. Complementary numerical solutions are also obtained using a quasilinearisation scheme. The scheme is found to be well suited to the problem, and good agreement is observed between the analytic and numerical results.
