Abstract Standard k--ε,low Reynolds' number Jones--Launder k--ε and RNG models were adopted to simulate the flow field of metal melt in three different prebaked anode cell designs, i.e.80 kA cell with three anode risers, 160 kA cell with two anode risers and 200 kA cell with four side anode risers. Moreover, the melt velocities were measured using iron rod dissolution method. The simulating results were discussed and were compared with measuring data. It is shown that the turbulent viscosity in low Reynolds' number model is smaller than that in standard k--ε model. Standard k--ε and RNG model predict better the flow field of metal melt. Furthermore, the preliminary conclusion is that the low Reynolds' number model is not suitable to calculate metal melt flow in cells if the current is greater than 80 kA.
