dc.description.abstractThis research work titledA STUDY ON MIXED CONVECTION FLOW IN DIFFERENT CHANNELS, is divided into three parts.The first part analytically simulates the mixed convection flow in the steady, laminar fully developed region of a parallel porous plate channel filled with porous material .The Darcy-Brinkman model and Boussinesq are employed. While the second part investigates analytical solutions for fully developed mixed convection flow in a vertical channel formed by two infinite vertical parallel plates partially filled with porous material.The third part studies the steady mixed convection flow in an annulus partially filled with porous material. In the second and third problems, the Brinkman-extended Darcy model is used to simulate momentum transfer in the porous region and the Navier-Stokes equation is used to simulate the momentum transfer in the clear fluid region. The clear fluid and porous regions are coupled by equating the velocity, temperature, heat flux and by considering shear stress jump condition at the interface.In the first part, the effect of suction/injection on mixed convection flow between vertical porous plates filled with porous material is investigated. The second part investigates the relative significance of the governing parameters on the velocity,interface velocity and temperature in the channel. While the third part studies the impact of the Darcy number and the adjustable coefficient in the stress-jump condition at the interface of fluid/porous layer on flow formation inside the annulus. Moreover,a dimensionless temperature 0  is introduced which is related to the usual Re Gr parameter. The exact solutions for momentum and energy equations obtained are presented graphically and discussed.en_US
