摘要
通过水槽试验,结合理论分析,研究丁坝附近的水流紊动。绘出了脉动动能分布的等值线图,把脉动动能的分布图分成4个区域,详细阐述了脉动动能的分布规律。进一步研究了坝长、流量及水深对丁坝附近水流脉动动能分布的影响,并分析其原因,深入探讨丁坝附近的水流紊动。
With the aid of model experiment and through theoretical analysis, turbulent characteristics of flow around spur dike are studied. After drawing the distribution isoline of pulsation kinetic energy, which is divided into four areas, the distribution disciplinarian of pulsation kinetic energy is expatiated. The influencing factors of pulsation kinetic energy such as length of spur dike, flux and depth of flow are analyzed systematically.
