Data from testing AirSWMM(v2.1) to a real-life network

This research provides a first assessment of the location of air pockets in a case study from the literature by using the developed AirSWMM. A pressure-driven analysis is implemented in the source code of AirSWMM(v2.0) to better simulate the nodal demand since this feature was not originally included in SWMM. Pressure-head results for different spatial discretisations are compared with collected field data to assess the best compromise between spatial discretisation and the results’ accuracy. The recommendations from international guidelines for the location of air release devices are compared to the predicted air pocket locations to assess if the numerical estimates are in agreement with the empirical evidence

本研究依托公开文献中的案例场景，运用自研的AirSWMM工具，首次完成了管网空气囊位置的评估分析。由于原生SWMM未集成压力驱动分析功能，研发团队在AirSWMM(v2.0)的源代码中嵌入该模块，以更精准地模拟节点需水过程。针对不同空间离散化方案得到的压力水头模拟结果，研究团队将其与收集的现场实测数据进行比对，以权衡空间离散化程度与模拟结果精度间的最优平衡点。此外，研究将国际指南中关于空气释放装置布设位置的建议，与模型预测的空气囊位置进行比对，以验证数值估算结果是否与实际经验相符。
