水平轴环流区环流高度的初步研究

Preliminary Study of Circulation Height with the Horizontal Axis

本文针对水平轴环流运动的特点 ,以槽沟中产生的水平轴环流为研究对象 ,通过水槽概化模型试验 ,在实测流速分布的基础上 ,分析了水平轴环流区环流高度随来流条件及槽沟边坡角度的变化规律 ,并提出了相应的水平轴环流高度的计算公式。

In this paper, the relation between the circulation height of the circulation flow with horizontal axis and the incident flow condition as well as the slope angle of the trench was systematically analyzed on the basis of the velocity distribution data observed by a series of model tests in flume, and the relevant formula of the circulation height was proposed. Moreover, the variation laws of the circulation flow strength was also analyzed.
