在目前国内雨水管道的设计中,检查井内局部损失通常被忽略。通过Fluent软件对检查井内水流情况进行三维流动仿真分析,得到部分类型检查井的局部损失系数,经分析,检查井内局部损失占沿程损失的比例远远大于10%,目前忽略检查井局部损失影响的设计处理方式将造成较严重的误差。
In the current domestic stormwater pipeline design, the local damage in the inspection well is usually neglected. Fluent software was used to simulate the three-dimensional flow in the inspection well to get the partial loss coefficient of some types of inspection wells. The ratio of local losses in the inspection well to the loss of the inspection well is far greater than 10%. At present, the influence of local losses in the inspection wells is neglected The design approach will result in more serious errors.
