摘要
To study the effect of magnetic pressure on the liquid metal pool, the system is analytically modeled by a surface contour method. With this method, the magnetic fringing field of a gapped coil is calculated analytically by an extrapolation method. Meltpool deformation is modeled using the static pressure equilibrium calculated over the liquid metal surface. The effect of different electromagnetic and hydrostatic parameters is taken into account. The resultant differential equation is solved by the use of the Green's function. To validate the analytical calculations, an experimental setup has been implemented. To study the experimental meltpool deformation, a metal with a low melting point temperature, known as Wood metal, is used. The implemented system includes a high AC current generator and a gapped inductor as a magnetic pressure applicator.
