Fluid flow and heat transfer analysis of Couette flow in a composite duct

This paper deals with a fully developed Couette flow through a composite channel, partially filled with a clear fluid and partially with a fluid-saturated porous medium. The flow occurs because of a moving plate, which bounds the clear fluid region. The porous region is bounded by a fixed plate. Assuming that the moving plate is adiabatic, and that the fixed plate is subject to a uniform heat flux, a boundary layer solution for the velocity and temperature fields is obtained.
