摘要

This computational study examines the combined effect of the anodeAnode-cathode arrangement and cathode roddingCathode rodding on the electrical current distributionCurrent distribution in liquid aluminiumAluminium. The results indicate that in the case of uniformUniform rodding, the horizontal currentHorizontal current is the least when the anodeAnode edge is slightly outside the cathode. The horizontal currentHorizontal current increases near the sidewall as the anodeAnode edge is shifted towards the centre. When the length of the rodding is reduced at the cathode end, the horizontal currentHorizontal current directed towards the sidewalls reduces. However, beyond a minimum rodding length, the horizontal currentHorizontal current changes the direction majorly towards the centre.
