横向槽沟内非均匀流的试验研究

Experimental Study on the No nuniform Flows in Lateral Trenches

  • 摘要: 以横向槽沟中产生的非均匀流为研究对象,通过水槽概化模型试验,在实测纵向流速分布的基础上,分析了不同来流条件及不同槽沟边坡角度下的槽沟内水面流速、槽底流速等沿程变化规律,同时还得到了计算槽沟内反向平均流速及正向平均流速的经验公式.

     

    Abstract: In this paper,taking the nonuniform flows in lateral trenches as research object,a series of schematic model tests in flume are used to study the variance laws of surface velocity and near-bottom velocity under the condition of different incident flow conditions and slope angles of trenches.Moreover,the relevant empiric formulas for calculating the negative mean velocity and the positive mean velocity are derived.
