TL;DR: In this article , the Soret effect on a moving MHD flow past an infinite vertical plate with variable temperature and mass diffusion was investigated. But the authors focused on the effect of flow parameters on an unsteady MHD free convective flow past the plate.

TL;DR: In this article, a numerical analysis of the MHD free convection and mass transfer flow of a dissipative fluid along a vertical plate with time-dependent plate velocity, the surface of which is exposed to a constant heat flux is presented.
Abstract: This paper presents a numerical analysis of the MHD free convection and mass transfer flow of a dissipative fluid along a vertical plate with time-dependent plate velocity, the surface of which is exposed to a constant heat flux. The non-linear system of partia l differential equations is numerically solved by the implicit finite differenc e scheme of Crank- Nicolson's type. The velocity, temperature and conc entration profiles for different values of plate velocity are plotted. The influence of the buoyancy ratio parameter, dissipation number, Grashof number , Prandtl number, Schmidt number and magnetic parameter on heat and m ass transfer are discussed. It is found that, the velocity as well as temperature increases with effects dissipation number. the velocity and temper ature decreases with increases in the magnetic parameter, while concentr ation profiles increases with increases in magnetic parameter. the velocity increases as well as the temperature and the concentration decreases with i ncreases buoyancy ratio parameter. The velocity increases as well as the te mperature and the concentration decreases with increases Grashof numb er.

TL;DR: In this paper, the spectrum of high Schmidt number passive scalar in forced homogeneous isotropic turbulence is studied through direct numerical simulations, and the influence of the form of the scalar forcing is also discussed.
Abstract: In this paper, the spectrum of high Schmidt number passive scalar in forced homogeneous isotropic turbulence is studied through direct numerical simulations. An hybrid spectral-particle method is used with a finer resolution of the scalar than of the momentum and large time-steps. This approach enables to perform a systematic analysis over a wide range of Schmidt numbers. Our results recover the theoretical scaling for the variance scalar spectrum, and its relationship with the value of the Schmidt number, for large, intermediate and small scales. The influence of the form of the scalar forcing is also discussed.

14 Apr 1999TL;DR: In this paper, the Schmidt number, Sc, and reaction order, n, were derived for a semi-infinite vertical plate, where the concentration of a species along the plate follows some algebraic law with respect to chemical reaction.
Abstract: Steady laminar natural convection flow over a semi-infinite vertical plate is examined in this paper. It is assumed that the concentration of a species along the plate follows some algebraic law with respect to chemical reaction. Similarity solutions may then be obtained for different orders of reaction. The fundamental parameters of this problem are the Schmidt number, Sc, and reaction order, n. Numerical results, based on the Fourth-order RungeKutta method, for Schmidt number ranging from 0.0 to 100.0 and reaction order from 0.0 to 1.5 are presented. When chemical reaction occurs, diffusion and velocity domains are seen to expand out from the plate. For large values of n, one may expect a smaller diffusion layer which, at fixed Schmidt number, is associated with increased velocity and reduced convection-layer.
