Heat transfer effects in a Couette flow through a composite channel partly filled by a porous medium with a transverse sinusoidal injection velocity and heat source

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 me- dium. 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 me- thod. The effects of various flow parameters such as, Prandtl number, suc- tion/injection parameter, permeability of the porous medium, heat source para- meter, and viscosity ratio parameter, 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.
