摘要：

The effects of trapped air on flow oscillations and pressure surges in a model trunk sewer-manhole system subject to rapid filling are investigated. The study reveals the detrimental impacts of entrapped air during severe storm events under which pipelines are likely overloaded. The results of the investigation indicated huge peak pressures and severe pressure oscillations inside the system.
