摘要
通过二维数值模拟研究了水力自控翻板闸门门顶门底同时淹没出流时的泄流能力,并结合以往翻板闸门工程水槽试验成果对计算结果进行分析。结果表明,计算结果拟合公式计算值和试验值较接近,可为翻板闸门的设计和运行中流量的估算提供参考。
Through a 2- D numerical simulation,the discharge capacity of the hydro-automatic flap gate under the outflow condition when both the top and the bottom of it are submerged is studied herein,and then the calculation result is analyzed in accordance with the achievement previously obtained from the flume experiment made for the flap gate project concerned. The result shows that the calculation value from the fitting formula is more closer to that from the experiment,thus can provide references for the design of the flap gate and the estimation of its discharge during operation.
