| 摘 要： | 为了改善量水槽在平原灌区应用受限的状况,利用鸽子翅膀截面曲线,通过仿生优化设计了一种鸽翼形量水槽,并通过模型试验研究不同流态下量水槽的水力特性.试验结果表明:自由出流时水深-流量的稳定关系在淹没出流时仍然存在;不同流态时,水跃发生位置不同,自由出流时,水跃发生在出口断面附近,淹没出流时,则在喉口附近;自由出流时的测流精度高于淹没出流,测流误差在2%~3%,但淹没出流的测流误差随着流量增大而减小;鸽翼形量水槽的临界淹没度均在0.850以上,最高可达0.933,具有较大的测流范围.鸽翼形量水槽的工作性能良好,可开展标准化设计和工程应用.

| Abstract: | In order to solve the problem of limited application of measuring flume in the plain irrigation area, a kind of measuring flume with pigeon wing shape was designed by using the contour of pigeon wings and bionic optimization design method, and the hydraulic characteristics of measuring flume under different flow patterns were studied by model test. The test results show that the stable relationship between water depth and flow rate still exists in the case of free flow; the location of hydraulic jump is different in different flow patterns; the hydraulic jump occurs near the exit section in the case of free flow, and near the throat in the case of submerged flow; the flow measurement accuracy in the case of free flow is higher than that in the case of submerged flow, and the flow measurement error is between 2% and 3%, but the flow measurement error decreases with the increase of flow rate in the case of submerged flow.The critical submergence of dove wing flume is above 0.850, and the maximum submergence is 0.933. The pigeon wing measuring flume has good performance, which can be used in stan-dardized design and engineering application. |
