Three-dimensional numerical computations for a single bubble rising in a liquid metal within a rectangular enclosure in a uniform vertical magnetic field are carried out In this study, the bubble shape, the velocity field and the electric current density field interact with one another under the influence of the vertical magnetic field This is a triple simultaneous problem The pressure and the electric potential fields are obtained with an iterative procedure by the HSMAC method The numerical results exhibit that the rising velocity of the bubble for the range of Hartmann number 0 75 owing to deceleration effect on the fluid flow by the magnetic field The bubble elongates in the direction of the uniform magnetic field because of the modification of the pressure distribution by the Lorentz forceread more

A continuum method for modeling surface tension
TL;DR: In this paper, a force density proportional to the surface curvature of constant color is defined at each point in the transition region; this force-density is normalized in such a way that the conventional description of surface tension on an interface is recovered when the ratio of local transition-reion thickness to local curvature radius approaches zero.
