铝电解槽侧部槽壳散热三维仿真模型研究

Study on the 3D heat transfer model of the aluminum reduction cell shells based on the method of simulation

以商业软件ANSYS为平台,建立了240kA预焙阳极铝电解槽槽壳热场的三维仿真模型,对其侧部散热进行了数值计算,并将计算结果与实测值进行比较,验证了模型的可靠性,得出了侧部槽壳散热的分布规律。充分考虑了槽壳结构对散热的影响,利用ANSYS辐射单元准确求解出各辐射换热面之间的角系数,使计算模型更加合理,为准确计算和分析铝电解槽侧部槽壳散热提供了一种可靠的方法和手段。

Based on the commercial software ANSYS, the 3D finite element model of the aluminum reduction cell shells was built and the heat loss from the side of the aluminum reduction cell was numerically simulated. The model is credible through comparing the tested data, and the laws of the aluminum reduction cell shells heat loss were obtained. The numerical simulation is in much accord with the fact, because the frame of the aluminum reduction call shells influencing heat loss is considered, and angle coefficient is accurately calculated by the software ANSYS. And these provide a credible method for study on the heat transfer of the aluminum reduction cell shells.
