TURBULENCE CHARACTERISTICS IN CONSECUTIVE BENDS

Funds: The project was supported by the National Natural Science Foundation of China (50979043, 50879042) and the Open Research Fund Program of State Key Laboratory of Hydroscience and Engineering (2010-ZY-3).
  • 摘要: 采用电磁流速仪, 在接近天然河道形态的连续弯道中, 对沿程断面上各点的脉动流速进行量测.根据测得的数据分析得到了紊动能谱、紊动强 度、紊动切应力、紊动能、紊动参数等的全断面分布.研究结果表明水流紊动主要集中在10 Hz以下,不同环流形式与各种紊动量之间会互相影响,边壁处纵向紊动强烈、横向和垂向紊动较弱.
