By this method, various pictures of flowing fluid in the three zones, i.e. the end effect zone, the block packing zone and the shell zone of RS dimple wire mesh packing and foam metal packing at different operating conditions were taken.

• 对旋转床内泡沫金属填料与RS波纹丝网填料下不同区域(填料进口区、填料主体区及填料外空腔区)及不同转速、液量等操作条件的流体流动状况进行拍照，得到大量清晰可辨的照片，最终获得旋转床内各流态及其分布等大量信息。
