各类化工设备器壁的影响称为壁效应。 这种影响主要是指靠近器壁的空间结构与其他部分有很大差别,器壁处的流动状况、传质、传热状况与主流体中也有很大差别。当采用实验规模的小型设备研究传质、传热、反应的规律时,器壁的影响远比大型设备为大。

⑤For this experiment bench, EHE inside the warehouse Room intermediate have a good fluid effect. But because of the wall effect the hybrid gas-solid flow that is near the wall is far less intensity among regions.
⑤对于本实验台,外置式换热器内各仓室中间位置流化效果较好,靠近边壁的区域由于边壁效应的影响,其混合和气固两相流动的剧烈程度远不如中间区域,因此中部的换热系数很明显大于两侧的换热系数。
