在本研究中，我们在一种特定尺寸的封闭式水泵吸水池的基础上进行改进设计，即在吸水池的吸 入管的底部加上一个Ｔ型台。改进的目的是为了减少并控制吸水池以及吸入管周围的旋涡。因为水泵吸水池 内部的流动状态是非常复杂的，特别是在吸入管的周围，分布着十分复杂的旋涡。这些旋涡的存在对整个系 统的流动状态会产生多种影响，可能会使泵站的性能恶化。为了验证这种改进型设计的实际效果以及得出改 进型吸水池内部的流动状态，我们采用粒子成像测速技术（ＰＩＶ）测量技术对吸入管附近的流场进行测量，并 对测量结果进行分析。
In this study, we developed an improved design based on a closed-size water pump of a specific size by adding a T-table to the bottom of the suction pipe of the water tank. The purpose of the improvement is to reduce and control the vortex and the vortex around the suction tube. Because the flow inside the pump sump is very complex, especially around the suction pipe, the distribution of a very complex vortex. The presence of these vortices can have a variety of effects on the flow of the entire system and can degrade pump performance. In order to verify the actual effect of this improved design and to derive the flow conditions inside the improved suction basin, we measured the flow field near the suction tube using Particle Imaging Velocimetry (PIV) measurement techniques and analyzed the results.
