Entropy analysis of generalized MHD Couette flow inside a composite duct with asymmetric convective cooling.

*(English)*Zbl 1391.76864Summary: The paper presents entropy analysis of MHD generalized Couette fluid flow inside a composite duct. The composite duct is composed of two parallel walls. The upper wall is uniformly moving impermeable plate, whereas the lower wall is porous strata of finite thickness with impermeable bottom. The upper plate and the bottom are asymmetrically convectively cooled. The solutions obtained for the velocity and the temperature are exploited to enumerate entropy generation. The effects of pertinent parameters on the quantities of interest are portrayed graphically and are discussed.
