    MHD FLOW AND HEAT TRANSFER IN A WILLIAMSON FLUID FROM A VERTICAL PERMEABLE CONE WITH THERMAL AND MOMENTUM SLIP EFFECTS: A MATHEMATICAL STUDY

    CH. Amanullaa,b,* , N. Nagendraa , M. Suryanarayana Reddyb

    Frontiers in Heat and Mass Transfer, Vol.8, pp. 1-11, 2017, DOI:10.5098/hmt.8.40

    Abstract A theoretical and computational study of the magneto hydrodynamic flow and free convection heat transfer in an electro-conductive polymer on the external surface of a vertical permeable cone under radial magnetic field is presented. Thermal and velocity (hydrodynamic) slip are considered at the vertical permeable cone surface via modified boundary conditions. The Williamson viscoelastic model is employed which is representative of certain industrial polymers. The non-dimensional, transformed boundary layer equations for momentum and energy are solved with the second order accurate implicit Keller box finite difference method under appropriate boundary conditions. Validation of the numerical… More >

    THERMAL AND MOMENTUM SLIP EFFECTS ON HYDROMAGNETIC CONVECTION FLOW OF A WILLIAMSON FLUID PAST A VERTICAL TRUNCATED CONE

    CH. Amanullaa,b,* , N. Nagendraa , M. Suryanarayana Reddyb

    Frontiers in Heat and Mass Transfer, Vol.9, pp. 1-9, 2017, DOI:10.5098/hmt.9.22

    Abstract In this article, the combined theoretical and computational study of the magneto hydrodynamic heat transfer in an electro-conductive polymer on the external surface of a vertical truncated cone under radial magnetic field is presented. Thermal and velocity (hydrodynamic) slip are considered at the vertical truncated cone surface via modified boundary conditions. The Williamson viscoelastic model is employed which is representative of certain industrial polymers. The governing partial differential equations (PDEs) are transformed into highly nonlinear, coupled, multi-degree non-similar partial differential equations consisting of the momentum and energy equations via appropriate non-similarity transformations. These transformed conservation More >
