摘要
通过概化模型试验,结合理论分析,研究了弯曲分汊河道的水流紊动。给出了脉动动能分布的等值线图,详细阐述了紊动强度在汊道内的分布规律。进一步研究了弯曲分汊河道内存在边滩和洲头低滩时,对水流紊动强度分布的影响,深入探讨弯曲分汊河道的水流紊动。
With the aid of generalized physical model experiment and through theoretical analysis,the turbulent characteristics of flow in bending braided channel are studied.After drawing the distribution isoline of pulsation kinetic energy,the distribution disciplinarian of intensity of turbulence is expatiated.The influencing factors of intensity of turbulence such as side flat and shoals at the head of river island are analyzed systematically.
