This study theoretically analyzes the heat transfer effects in a 3-D Couette flow through a composite parallel porous plate channel partly filled by a porous medium. The flow is 3-D in the channel because of the application of a transverse sinusoidal injection velocity of a particular form at the lower stationary plate. The governing equations are solved using a perturbation series expansion method. The effects of various flow parameters such as, Prandtl number, suction/injection parameter,
