Experimental and theoretical studies of the motion generated by a two-frequency magnetic field at the free surface of a gallium pool

Efficient Melt Stirring Using Pulse Sequences of a Rotating Magnetic Field: Part I. Flow Field in a Liquid Metal Column

“…[1][2][3][4][5][6] The requirements arising from the particular metallurgical or casting operation are manifold. For example, the electromagnetic stirring should provide an efficient mixing of the melt or counterbalance buoyancy-driven flows.…”

Kinetics of the actinides–lanthanides separation: mass transfer between molten fluorides and liquid metal at high temperatures

“…Table 3 shows the values of k Zr versus different surface agitation rates represented by the values of the surface velocity x 2 g 0 where x 2 and g 0 are respectively the low angular frequency of the electrical induction current and the characteristic height of the fluctuation of the interface. The measurement of the characteristic height was previously described [11] and consists of a pin placed above the surface of the liquid metal. The study of the deformation is made through this pin that is connected to a recording system.…”

Interface, Flows and Transfer in an Electromagnetic Process Devoted to Liquid/Liquid Extraction

“…The case of a cylindrical gallium pool subjected to a magnetic field generated by an inducting current of the form given by Equation (1) was studied by Perrier et al [4], who demonstrated that the surface of the pool behaves as a forced oscillator; therefore, the choice of the f 2 value imposes the way the free surface oscillates. Because the kinetics of the transfer depend on the chosen frequency, the next section of this paper is devoted to interface behavior versus modulation frequency f 2 .…”

“…[11] Before calculating the shape of the interface, the VOF model had been validated in measurements performed on a gallium pool. [4] In Figure 6, the experimental heights of the domes of a gallium pool are compared to numerical results given by the VOF model for different values of the magnetic field. It appears that the numerical model correctly reproduces the shape of the free surface and the heights of the domes are well predicted.…”
