铝电解槽内保持良好的热平衡可以减少铝电解过程中的能耗,而氧化铝周期性的下料会破坏电解槽热平衡。建立铝电解槽电解质浓度-热场瞬态模型,在精确模拟氧化铝浓度分布的基础上,研究下料期间电解质温度及热平衡的变化趋势。结果表明:氧化铝下料时,电解质极距层局部温度降低5℃左右,上表面附近区域最多降低十几度;下料结束20 s内,逐渐恢复到正常温度;氧化铝下料会打破电解质内的热平衡,其中部分热量(最高达300 k W)用来加热氧化铝颗粒;20 s后,电解质会达到新的热平衡状态。

青藏高原大地形的热力强迫作用对亚洲夏季风的形成和发展具有重要的影响.本文利用较高分辨率的WRF区域模式,探讨了高原不同区域(斜坡和平台)的地形加热分别对南亚夏季风和东亚夏季风的影响.结果表明:高原南部喜马拉雅山脉的斜坡地形加热对其周围局地的环流形势和降水影响十分明显,是南亚夏季风北支分量形成和维持的主导因子,也是斜坡上气流爬坡和降水发生的必要条件.斜坡加热对东亚夏季风也有明显的增强作用,它不仅加强了中国东部低空西南季风环流,还会造成北部南下的异常干冷空气的响应.斜坡上的地形加热作用也是对流层高层暖中心位置维持在斜坡上空的一个重要原因.而高原平台加热对季风环流和降水的影响虽然没有喜马拉雅山脉斜坡加热那么显著,但是对南亚夏季风的影响范围更广,对经向哈得来环流影响更明显,能够调控高原以外更远处热带洋面上的西南季风环流.通过比较高原不同区域地形加热条件下的多种季风指数,进一步表明了高原地形加热对南亚和东亚夏季风均有增强作用,但是高原不同区域的地形加热对两类夏季风子系统又会产生不一样的影响.
