This study theoretically analyzes the heat transfer effects in a three
dimensional Couette flow through a composite parallel porous plate channel
partly filled by a porous medium. The flow is three dimensional 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 (Pr),
suction/injection parameter (λ), permeability of the porous medium (K), heat
source parameter (S), and viscosity ratio parameter (Ф1), are investigated on
temperature distribution in the composite channel and rate of heat transfer
at the upper moving plate and at the fluid-porous medium interface, and
discussed graphically.
