Method for propagating vibratory motion into a conductive fluid and using the method to solidify a melted metal

摘要

A static magnetic field and a wave are applied to an electrically conductive fluid so as to satisfy the mathematical expressionwhere f is the frequency (Hz) of the applied wave, sigma is the electrical conductivity (S/m) of the conductive fluid, rho is the density (kg/m<3>) of the conductive fluid, and B is the strength of the applied static magnetic field (T), to thereby generate and propagate vibratory motion into the conductive fluid.
