Flow transitions in vacuum arc remelting
It show that the structure of an ingot produced by vacuum arc remelting depends critically on the temperature distribution within the liquid portion of the partially solidified ingot. This, in turn, depends on the fluid motion in the pool, since the dominant mechanism for transporting heat is convection. There are three primary sources of motion: buoyancy ; Lorentz forces arising from the passage of current through the pool ; and Lorentz forces arising from the presence of external inductors. These forces are constantly in competition with each other, and each tends to induce a quite different distribution of velocity and temperature.
