Abstract
A physical model (approximately one-tenth scale and operated at 1000 A) was constructed to simulate the electromagnetically driven flow occurring in Hall cells. The model contained Wood’s metal, in which magnetic fields and velocities were measured, as the single liquid. Data have been generated for (future) comparison with mathematical models of Hall cells. The model has also proved useful in examining the effects of cell changes and upsets long thought by operators to have an influence on cell performance. Effects of current maldistribution in the “collector bars,” “cold” anodes, “muck,” and alternative bus-bar arrangements have been observed. In many cases, these effects can be predicted qualitatively from an examination of the model’s magnetic field.
