Experimental and numerical analysis of a water emptying pipeline using different air valves
(MDPI AG, 2017)
The emptying procedure is a common operation that engineers have to face in pipelines. This generates subatmospheric pressure caused by the expansion of air pockets, which can produce the collapse of the system depending ...
Effect of a commercial air valve on the rapid filling of a single pipeline: A numerical and experimental analysis
(MDPI AG, 2019)
The filling process in water pipelines produces pressure surges caused by the compression of air pockets. In this sense, air valves should be appropriately designed to expel sufficient air to avoid pipeline failure. Recent ...
Computational fluid dynamics for sub-atmospheric pressure analysis in pipe drainage
(Taylor and Francis Ltd., 2019)
The occurrence of sub-atmospheric pressure in the drainage of pipelines containing an air pocket has been known as a major cause of several serious problems. Accordingly, some system malfunction and pipe buckling events ...
Rigid water column model for simulating the emptying process in a pipeline using pressurized air
(American Society of Civil Engineers (ASCE), 2018)
This paper presents a mathematical model for analyzing the emptying process in a pipeline using pressurized air. The rigid water column model (RWCM) is used to analyze the transient phenomena that occur during the emptying ...
