Summary:
Natural convection heat transfer in the porous cavity with arc shape wall filled with nanofluid is studied numerically. The right arc shape wall of the cavity is heated at constant temperature (Th) while the left wall is kept cold at constant temperature (Tc), and the other horizontal walls are thermally insulated. The governing equations of the heat transfer and nanofluid flow are solved Flex PDE software. A temperature-independent nanofluid properties model is adopted. The investigated parameters are the nanoparticles volume fraction Ø = (0 - 0.2), Rayleigh number Ra (10 - 1000), and arc center Ce (1 - ∞). The results are presented by the contour of streamlines, isotherms, and the average Nusselt number. The results have shown that the average Nusselt number decreases with increasing Ce and increases with increasing Ra and Ø.
