| 摘 要： | 针对两台机组共用的尾水调压室进行了水力特性试验，研究了尾水调节室流量经、阻抗孔口水中水流方向及孔口开关形状对尾水调压室水头损失系数的影响，试验结果表明，阻抗式不调压室的水头损失系数并不是现有文献所描述的那种仅与孔口形状充方向有关的常数，而一个与流量比有关的变量，文中给出了不同阻抗也口的高压室水头损失系数关于流量经的最小二乘拟合公式。

| Abstract: | The experiment on the hydraulic characteristics of rectangular tailrace surge tank shared by two units is described in this paper. The effects of the discharge ratio, the flow direction, the orifice size and configuration on the head loss coefficients are discussed. The study shows that the head loss coefficients of the surge tank are not constants, but variables determined by the orifice configuration, flow direction and discharge ratio. The best fitting formulae are proposed for the head loss coefficients. |

| Keywords: | surge tank discharge ratio throttled orifice head loss coefficients |
