掺气分流墩墩头的动水压强特性研究

对掺气分流墩墩头的动水压强特性进行了试验研究，以求了解墩头的抗空蚀性能及动水压强特性。试验结果得出：时均压强P／Pman沿墩高和Cp沿横断面的分布规律；墩头轴线与来流有夹角时Cp沿横断面的分布规律；墩头壁压脉动压强特性，在墩后充分供气时，墩头的空化特性。

Study on the Characteristics of Hydrodynamics Pressure on the Front of Aeration-Baffle

Experimental researches of characteristics of hydrodynamic pressure on the front of aeration-baffle are presented in this paper to obtain the properties of the aeration-baffle resistant to cavitation. The experimental results provide the f o llowing: the law of distribution of mean pressure P/P max in the vertic al direction and of mean pressure coefficient C p on the cross-section of a eration-baffles; the law of distribution of C p on the cross section when the flowing direction is not parallel to the axis of the aeration-baffle; the c h aracteristics of fluctuating pressure on the front surface of the aeration-baff l e and the characteristics of cavitation of the front of the aeration-baffle whe n air is completely aerated from the back of the aeration-baffle.
