Heat transfer, fluid flow and entropy generation due to buoyancy forces in a 2-D enclosure equipped with a conductive baffle and containing Al2O3nanofluid is carried out using different conductivities of baffle and different concentrations of nanoparticles. The bottom wall is subjected to constant hot temperature. The right and left vertical walls are maintained at lower temperature and the top wall is insulated. The finite volume method is used to solve the governing equations and calculations were performed for Rayleigh number from 10 3 to 10 6 , thermal conductivity ratio from 0.01 to 100 and volume fraction of nanoparticles from 0 to 0.2. An increase in mean Nusselt number and a decrease of the total entropy generation were found with the increase of volume fraction of nanoparticles for the whole range of Rayleigh number.

“…Since the system of the governing equations (15)- (18) as well as the boundary conditions (36)- (38) are coupled and nonlinear, it is necessary to use a numerical method to solve them. To do this, the numerical Galerkin finite element approach is applied to do the weak form of the equations in the deformable grid system of ALE.…”

“…nanofluids) in the range of sizes 1050 nm (Chol 1995). Due to the small sizes and very large specific surface areas of the nanoparticles, nanofluids have superior properties like high thermal conductivity, minimal clogging in flow passages, longterm stability and homogeneity (Nasrin and Alim 2013). Thus, nanofluids have a wide range of potential applications such as in electronics, automotive, and nuclear applications where improved heat transfer or efficient heat dissipation is required.…”

The problem of darcian natural convection in inclined square cavity partially filled between the central square hole filled with fluid and inside a square porous cavity filled with nanofluid is numerically studied using the finite element m ethod. The left vertical wall is maintained at a constant hot temperature T h and the right vertical wall is maintained at a constant cold temperature T c , while the horizontal walls are adiabatic. The governing equations are obtained by applying the Darcy model and Boussinesq approximation. COMSOL's finite element method is used to solve the non-dimensional governing equations together with the specified boundary c onditions. The governing parameters of this study are the Rayleigh number (10 3 ≤ Ra ≤ 10 7 ), the Darcy number (10 −5 ≤ Da ≤ 10 −3 ), the fluid layer thickness (0.4 ≤ S ≤ 0.8) and the inclination angle of the cavity ( 0 • ≤ ω ≤ 6 0 • ). The results for the values of the governing parameters in terms of the streamlines, isotherms and average Nusselt number will be presented. The convection is shown to be inhibited by the presence of the hole insert. The thermal property of the insert and the size have opposite influence on the convection. The results have possible applications in heat-removal and heat-storage fluid-saturated porous systems.
