    MHD Natural Convection in a Nanofluid-filled Enclosure with Non-uniform Heating on Both Side Walls

    Imen Mejri1,2, Ahmed Mahmoudi1, Mohamed Ammar Abbassi1, Ahmed Omri1

    FDMP-Fluid Dynamics & Materials Processing, Vol.10, No.1, pp. 83-114, 2014, DOI:10.3970/fdmp.2014.010.083

    Abstract This study examines natural convection in a square enclosure filled with a water-Al2O3 nanofluid and subjected to a magnetic field. The side walls of the cavity have spatially varying sinusoidal temperature distributions. The horizontal walls are adiabatic. A Lattice Boltzmann method (LBM) is applied to solve the governing equations for fluid velocity and temperature. The following parameters and related ranges are considered: Rayleigh number of the base fluid, from Ra=103 to 106, Hartmann number from Ha=0 to 90, phase deviation (γ =0, π/4, π/2, 3π/4 and π) and solid volume fraction of the nanoparticles between ø = 0 and 6%.… More >

    Optimal Formulation of Nanofluids for Maximum Free Convection Heat Transfer from Horizontal Isothermal Cylinders

    Massimo Corcione1

    FDMP-Fluid Dynamics & Materials Processing, Vol.7, No.2, pp. 175-200, 2011, DOI:10.3970/fdmp.2011.007.175

    Abstract Free convection heat transfer in nanofluids from horizontal isothermal cylinders is investigated theoretically. The main idea upon which the present work is based is that nanofluids behave more like a single-phase fluid rather than like a conventional solid-liquid mixture. This assumption implies that all the convective heat transfer correlations available in the literature for single-phase flows can be extended to nanoparticle suspensions, provided that the thermophysical properties appearing in them are the nanofluid effective properties calculated at the reference temperature. In this connection, two empirical equations, based on a wide variety of experimental data reported in the literature, are proposed… More >

    Rayleigh-Marangoni Instability of Binary Fluids with Small Lewis Number and Nano-Fluids in the Presence of the Soret Effect

    A. Podolny1,2, A. Nepomnyashchy3, A. Oron4

    FDMP-Fluid Dynamics & Materials Processing, Vol.6, No.1, pp. 13-40, 2010, DOI:10.3970/fdmp.2010.006.013

    Abstract A general model for two-component transport phenomena applicable for both nanofluids and binary solutions is formulated. We investigate a combined long-wave Marangoni and Rayleigh instability of a quiescent state of a binary (nano-) liquid layer with a non-deformable free surface. The layer is heated from below or from above. The concentration gradient is induced due to the Soret effect. A typical behavior of monotonic and oscillatory instability boundaries is examined in the limit of asymptotically small Lewis numbers and poorly conducting boundaries in the two important long-wave domains k~Bi1/2and k~Bi1/4.
