Title: Study on Aerator of Hydraulic Tunnel with Low Fr Number and Slight Slope
Abstract: With the characteristics of high flow velocity, low Fr number and slight slope of hydraulic tunnel, the backwater frequently occurs in the downstream of aerated cavity, so the aerator design of hydraulic tunnel is difficult. The model investigation and theory analysis are used to study the aerator. By comparing the height, slope and type of aerator, the influences of those factors on backwater, aerated volume and flow pattern are analyzed. The formula between the critical Fr number and the aerator height is obtained and the shape optimization method of aerator is generalized. The research results have been applied in actual hydraulic projects.
