Abstract: A water model was constructed with an inner diameter and depth 1/6.5 of those of the copper converter bath in Guixi Smelter. The length of the model was cut shorter containing 5 tuyeres. Modified Froud numbers for model and prototype were equal to fulfill the dynamic similarity. The void fraction in the bath was measured using the electroresistivity probe method in cases of using a single tuyere as four tuyeres. In the lower region near tuyeres, the void fraction showed a distribution similar with Gaussian function in horizontal direction, above this region, it became uniform. Near the two ends, the void fraction decreased linearly with decreasing distance to two vertical walls.
Key words: void fraction; distribution; copper converter
