| 摘 要： | 针对透水框架附近的流场分布规律的相关问题,通过采用高精度河流动力学水槽试验,利用基于变频技术的DCMS控制系统,进行单个透空四面体模型试验。试验在透空四面体周围布置972个测点,每个测点采用旋桨式光电流速仪测量。通过与无框架流场的对比,分析横断面流速沿垂直水流方向和沿高度方向的变化规律,得到透空四面体周围流速分布规律和具体减速、增速部位、平均减速率,揭示了透空四面体对水流扰动作用。

| Abstract: | Issues related to the flow field distribution of permeable frame near the river dynamics by using high-precision tank testing,the use of control systems based DCMS inverter technology,carried out through a single empty tetrahedral model test.Test through the air around the tetrahedral arrangement of 972 measuring points,each measuring point using propeller photoelectric velocity measurement.By comparison with frameless flow field,cross-sectional analysis of the flow velocity in the vertical direction and the height direction of the law of change,has been through the air velocity distribution in tetrahedral surrounding concrete and deceleration,growth area,the average deceleration rate,revealed through empty tetrahedral water flow disturbance. |

| Keywords: | transparent tetrahedral deceleration effect deceleration parts average reduction rate |
