Test results show that the eichhornia crassipe has influences on the time average velocity and Reynolds stress, and different cropping patterns have different influences. 试验结果表明,凤眼莲对各向时均流速和雷诺应力的分布影响明显,且不同种植方式的影响程度也不同。
The Reynolds stress model was used to simulate the flow field during the filtration and back pulse process in the ceramic filter vessel containing three filters. 摘要用雷诺应力模型模拟了含有三根滤管的过滤器内过滤和反吹的整个过程的流场。
