封闭管道系统中的间歇泉的特点是空气和水的混合物通过落井爆炸性释放。间歇泉经常在合流下水道系统 (CSS) 中作为合流下水道溢流 (CSO) 的爆炸形式观察到。在目前的工作中，首次使用三维计算流体动力学（CFD）模型对下水道间歇泉现象的流动特性进行了数值研究。传统上，与下水道间歇泉相关的流动过程的研究是通过物理实验和一维或二维数值模型进行的。然而，无可否认，下水道间歇泉是三维的，因此需要 3D 模型来进一步了解这种现象。 CFD 模型使用展示下水道间歇泉特征的实验进行校准。
A geyser in a closed conduit system is characterized by an explosive release of a mixture of air and water through a drop shaft. Geysers are often observed in combined sewer systems (CSSs) as an explosive form of combined sewer overflows (CSOs). In the present work, the flow characteristics of sewer geyser phenomenon are studied numerically using a three-dimensional computational fluid dynamics (CFD) model for the first time. Traditionally, investigations of flow processes associated with sewer geysers are conducted through physical experiments and one or two-dimensional numerical models. However, sewer geysers are undeniably three-dimensional, hence 3D models are necessary to gain further understanding of the phenomena. The CFD model was calibrated using an experiment that exhibit characteristics of sewer geysers.
