A parametric sensitivity analysis of numerically modelled piston-type filling and emptying of an inclined pipeline with an air valve
Coronado Hernández, Óscar Enrique; Fuertes Miquel, Vicente S.; Besharat M.; Ramos H.M. (BHR Group Limited, 2018)Filling and emptying operations should be planned by engineers in operational stages to prevent a system failure depending on reaching extreme low pressure values. In this sense, a compression of an air pocket produces ... -
Backflow air and pressure analysis in emptying a pipeline containing an entrapped air pocket
Besharat M.; Coronado Hernández, Óscar Enrique; Fuertes Miquel, Vicente S.; Viseu M.T.; Ramos H.M. (Taylor and Francis Ltd., 2018)The prediction of the pressure inside the air pocket in water pipelines has been the topic for a lot of research works. Several aspects in this field have been discussed, such as the filling and the emptying procedures. ... -
CFD and 1D simulation of transient flow effect on air vessel
Besharat M.; Coronado Hernández, Óscar Enrique; Fuertes Miquel, Vicente S.; Viseu M.T.; Ramos H.M. (BHR Group Limited, 2018)The estimation of unsteady parameters in two-phase condition is crucial for the safety and reliability of the hydraulic systems. There are plenty of one-dimensional (1D) simulation tools for unsteady flow estimation being ... -
Computational fluid dynamics for sub-atmospheric pressure analysis in pipe drainage
Besharat M.; Coronado Hernández, Óscar Enrique; Fuertes Miquel, Vicente S.; Viseu M.T.; Ramos H.M. (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 ... -
Effect of a commercial air valve on the rapid filling of a single pipeline: A numerical and experimental analysis
Coronado Hernández, Óscar Enrique; Besharat M.; Fuertes Miquel, Vicente S.; Ramos H.M. (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 ... -
Subatmospheric pressure in a water draining pipeline with an air pocket
Coronado Hernández, Óscar Enrique; Fuertes Miquel, Vicente S.; Besharat M.; Ramos H.M. (Taylor and Francis Ltd., 2018)An air pocket’s behaviour inside of a pipeline during transient conditions is of great importance due to its effect on the safety of the hydraulic system and the complexity of modeling its behaviour. The emptying process ...
