本实验是利用粒子成像测速技术来定量测量水槽模型中叶栅绕流产生的流场的．水槽模型是模拟大型水槽设备而设置的，这种大型水槽为我国研制出具有减阻、减噪、减振动等高综合性能的舰船、潜艇和水下兵器提供一种研究实验途径．
This experiment is the use of particle imaging velocity measurement technique to quantitatively measure the flow field generated by flow around the cascade in the tank model. The sink model is set up to simulate large sink equipment. This large sink provides a research and experimental approach for the development of warships, submarines and underwater weapons that have such high comprehensive performance as drag reduction, noise reduction and vibration reduction in China.
