Abstract

Flow discharge over side-weirs in rectangular channels derived by the De Marchi equation and discharge coefficient for the flow has been estimated through many experimental investigations. In this study the discharge coefficient for the dischalge over the side-weir along the main channel with side slope of 1 to m is obtained from experimentally and theoretically. An empirical formula of discharge coefficient for the considering flow is proposed as functions of Froude number and side slope of the main channel for the range of F1=0.3-0.8 and m=0-0.7.

Abstract

流下方向に水路幅が緩やかに拡幅する開水路漸拡流の流速分布がX型 Hot-film 流速計によって測定された. その結果, 形状損失係数のオーダーは Diffuser のものに類似していること, 主流速の水平方向分布は内層では log 則によって, 外層では Goertler の平面噴流式によって表現できること, 主流速の鉛直方向分布は内層では log 則によって, 外層では log-wake 則によって表現できること, さらに, 3次元流況として, 水路幅の拡幅に伴い底面渦が水平方向に伸張して主流速分布を変形させていること, 乱れエネルギーが壁面より多少離れた領域で増加することなどが明らかにされた.
