应用标准κ-ε双方程、低Reynolds数Jones-Launderκ-ε模型与RNGκ-ε模型分别对三种不同进电方式(四点进电的200 kA槽、两点进电的160 kA槽以及三点进电的80 kA槽)的预焙阳极Al电解槽内的Al液流场进行了数值仿真,并且应用铁棒溶蚀法对相应工况下的Al液流场进行了工业测试.通过对计算结果和测试结果的比较与分析,可以得出:与标准κ-ε模型相比较,低Reynolds数模型具有较小的湍流粘度;标准κ-ε模型与RNG模型用于Al液流场的数值仿真时,其计算结果均有较高的可靠性.并初步得出在电流强度大于80 kA的Al电解槽中,Al液流动的计算不适宜应用低Reynolds数模型.
