  • radiation effect on free convection laminar flow along a vertical flat plate with streamwise sinusoidal surface Temperature
    Mathematical and Computer Modelling, 2011
    Co-Authors: Md Mamun Molla, Suvash C Saha, M A Hossain
    Abstract:

    The effect of thermal radiation on a steady two-dimensional natural convection laminar flow of viscous incompressible optically thick fluid along a vertical flat plate with streamwise sinusoidal surface Temperature has been investigated in this study. Using the appropriate variables, the basic governing equations are transformed to convenient form and then solved numerically employing two efficient methods, namely, the Implicit Finite Difference method (IFD) together with the Keller box scheme and Straight Forward Finite Difference (SFFD) method. The effects of the variation of the physical Parameters, for example, conduction-radiation Parameter (Planck number), surface Temperature Parameter, and the amplitude of the surface Temperature, are shown on the skin-friction. Heat transfer rate is shown quantitatively and numerically. Velocity and Temperature profiles as well as streamlines and isotherms are also presented and discussed for the variation of the conduction-radiation Parameter. It is found that both skin-friction and rate of heat transfer are enhanced considerably by increasing the values of conduction radiation Parameter, R"d.

  • entropy analysis for viscoelastic magnetohydrodynamic flow over a stretching surface
    International Journal of Non-linear Mechanics, 2010
    Co-Authors: Soraya Aiboud, Salah Saouli
    Abstract:

    Abstract This paper presents the application of the second law analysis of thermodynamics to viscoelastic magnetohydrodynamic flow over a stretching surface. The velocity and Temperature profiles are obtained analytically using the Kummer's functions and used to compute the entropy generation number. The effects of the magnetic Parameter, the Prandtl number, the heat source/heat sink Parameter and the surface Temperature Parameter on velocity and Temperature profiles are presented. The influences of the same Parameters, the Hartmann number, the dimensionless group Parameter and the Reynolds number on the entropy generation are also discussed.

  • similarity solutions for flow and heat transfer of a quiescent fluid over a nonlinearly stretching surface
    Journal of Materials Processing Technology, 2008
    Co-Authors: Rafael Cortell Bataller
    Abstract:

    Abstract This paper presents a numerical analysis in connection with the boundary layer flow induced in a quiescent fluid by a stretching sheet with velocity u w ( x ) ∼  x 1/3 along with heat transfer. The surface Temperature is assumed to have a power-law variation. The viscous dissipation and thermal radiation are considered in the energy equation. The governing partial differential equations are converted into ordinary ones by a similarity transformation. The variations of dimensionless surface Temperature as well as flow and heat transfer characteristics with the governing Parameters are graphed and tabulated. Two cases are studied, namely, (i) the sheet with prescribed surface Temperature (PST case) and (ii) the sheet with prescribed heat flux (PHF case). Similarity solutions of the aforementioned problem are given for two values of the surface Temperature Parameter m , namely, m  = 2/3 in the PST case and m  = 1/3 in the PHF case. Moreover, the mechanical characteristics of the corresponding flow are also presented.
