Abstract

The influences of sludge on horizontal electric current (HEC) in metal pad of cell were analyzed using a 3D model. The results show that the sludge located in the center has small influence on the HEC. And the sludge located in the side has great effect on the HEC. As the length of sludge increases, the negative peak move from the side to the middle. Moreover, it produces a large positive peak close to the side. The sludge located in side has small influence on the cathode voltage drop than that of the sludge located in center.
