Z形薄壁堰過流能力試驗(yàn)
[Abstract]:In view of the fact that the flow characteristics and overcurrent capacity of Z Weir have not been reported, in order to study the overflow capacity of Z Weir, six Weir schemes and 12 groups of flow rate hydraulic model tests have been carried out in order to study the over flow capacity of Z Weir. The results show that the excess flow capacity of Z Weir is greater than that of straight Weir, and the larger the widening ratio of Z Weir is, the greater the discharge expansion multiple is, and the general Weir flow formula can be used to calculate the flow rate of Z Weir, and the comprehensive flow coefficient and the depth of the Weir, the height and the length of the Weir can be calculated. The width of the front Weir and the width of the Weir are related to each other. The widening ratio, the bigger the ratio of the width to the width of the Weir, the greater the discharge coefficient, and the greater the ratio of the water depth to the height of the Weir, the smaller the flow coefficient. Based on the experimental data, a formula for estimating the flow coefficient of Z-shaped Weir considering the ratio of water depth on Weir to Weir height, the ratio of width to width, and the ratio of Weir width to width before and after is given.
