The fan-shaped central revolving gate is a new type of gate with a significantly different flow pattern from the traditional gate. In order to study the hydrodynamic pressure characteristics of the fan-shaped central revolving gate, model experiment was conducted on the different opening coefficients of the gate based on the 60 m span gate of Wusongjiang regulation project and its energy dissipation design conditions, and the time-average pressure, average fluctuation amplitude, pulsation intensity and spectral characteristics under different opening coefficients were analyzed. The results show that the time-average pressure of the gate blade is positive pressure at each opening coefficient, and the overall pulsating pressure amplitude is relatively stable. The pulsating pressure of each measuring point is close to normal distribution under different opening coefficients. The pulsation intensity changes with the change of the opening and measuring point position. With the increase of the opening coefficient, the pulsation intensity presents a trend distribution of decreasing first and then increasing, and the pulsation intensity belongs to the low-frequency pulsation. The change of the measuring point position in the width direction will affect the pulsation intensity of the measuring point, and the center line pulsation intensity can be used instead of the whole gate pulsation intensity.

鉴于扇形中枢旋转门是一种结构新颖的闸门,其过流流态与传统闸门有显著区别,为研究扇形中枢旋转门的动水压强特性,基于吴淞江整治工程60 m大孔闸及其消能设计工况,对闸门不同开度系数进行模型试验,分析了不同开度系数条件下的时均压强、平均波动幅度、脉动强度、频谱特性。结果表明,各开度系数下,门叶时均压强均为正压;总体脉动压强幅值较平稳,各测点在不同开度系数下脉动压强接近正态分布;脉动强度大小随开度和测点位置的变化而变化,随着开度系数的增大,脉动强度呈先减小后增大的趋势分布,脉动压强属于低频脉动;宽度方向测点位置的变化会对测点脉动强度的大小产生影响,可用中线位置脉动强度代替整体模型脉动强度。

鉴于扇形中枢旋转门是一种结构新颖的闸门,其过流流态与传统闸门有显著区别,为研究扇形中枢旋转门的动水压强特性,基于吴淞江整治工程60 m大孔闸及其消能设计工况,对闸门不同开度系数进行模型试验,分析了不同开度系数条件下的时均压强、平均波动幅度、脉动强度、频谱特性。结果表明,各开度系数下,门叶时均压强均为正压;总体脉动压强幅值较平稳,各测点在不同开度系数下脉动压强接近正态分布;脉动强度大小随开度和测点位置的变化而变化,随着开度系数的增大,脉动强度呈先减小后增大的趋势分布,脉动压强属于低频脉动;宽度方向测点位置的变化会对测点脉动强度的大小产生影响,可用中线位置脉动强度代替整体模型脉动强度。

The fan-shaped central revolving gate is a new type of gate with a significantly different flow pattern from the traditional gate. In order to study the hydrodynamic pressure characteristics of the fan-shaped central revolving gate, model experiment was conducted on the different opening coefficients of the gate based on the 60 m span gate of Wusongjiang regulation project and its energy dissipation design conditions, and the time-average pressure, average fluctuation amplitude, pulsation intensity and spectral characteristics under different opening coefficients were analyzed. The results show that the time-average pressure of the gate blade is positive pressure at each opening coefficient, and the overall pulsating pressure amplitude is relatively stable. The pulsating pressure of each measuring point is close to normal distribution under different opening coefficients. The pulsation intensity changes with the change of the opening and measuring point position. With the increase of the opening coefficient, the pulsation intensity presents a trend distribution of decreasing first and then increasing, and the pulsation intensity belongs to the low-frequency pulsation. The change of the measuring point position in the width direction will affect the pulsation intensity of the measuring point, and the center line pulsation intensity can be used instead of the whole gate pulsation intensity.
