丁坝附近区域水流动能修正系数研究

Study on correction coefficient of flow kinetic energy near groyne

为研究丁坝附近水流动能修正系数的变化规律,以加单丁坝的水槽为对象进行实验,研究丁坝附近断面动能修正系数的变化,得出动能修正系数与纵向距离、丁坝坝长、丁坝挑角及水流流量之间的关系,并以实验数据为依据,建立了计算动能修正系数的数学公式。

Taking the water tank of Jiadan groyne as experimental object for study the variation of sectional kinetic energy correction coefficient near groyne, the relation between kinetic energy correction coefficient and longitudinal distance, groyne length, groyne bridging angle and discharge, the mathematic formula for calculation of kinetic energy correction coefficient is sets up on basis of experimental data.
