Analysis of Sub-Atmospheric Pressures during Emptying of an Irregular Pipeline without an Air Valve Using a 2D CFD Model

Hurtado-Misal, Aris D.; Hernández-Sanjuan, Daniela; Coronado-Hernández, Oscar E.; Espinoza-Román, Héctor; Fuertes-Miquel, Vicente S. (MDPI AG, 2021-09)

[EN] Studying sub-atmospheric pressure patterns in emptying pipeline systems is crucial because these processes could cause collapses depending on the installation conditions (the underground pipe covering height, type, ...
Assessment of Steady and Unsteady Friction Models in the Draining Processes of Hydraulic Installations

Coronado-Hernández, Oscar E.; Derpich, Ivan; Fuertes-Miquel, Vicente S.; Coronado-Hernández, Jairo R.; Gatica, Gustavo (MDPI AG, 2021-07)

[EN] The study of draining processes without admitting air has been conducted using only steady friction formulations in the implementation of governing equations. However, this hydraulic event involves transitions from ...
Experimental and Numerical Analysis of a Water Emptying Pipeline Using Different Air Valves

Coronado-Hernández, Oscar Enrique; Vicente S. Fuertes-Miquel; Besharat, Mohsen; Ramos, Helena M. (MDPI, 2017-02)

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 ...
Subatmospheric pressure in a water draining pipeline with an air pocket

Coronado-Hernández, Oscar Enrique; Fuertes-Miquel, Vicente S.; Besharat, Mohsen; Ramos, Helena M. (Taylor & Francis, 2018)

[EN] 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 ...
The crucial importance of air valve characterization to the transient response of pipeline systems

Tasca, Elias; Karney, Bryan; Fuertes-Miquel, Vicente S.; Dalfré Filho, José Gilberto; Luvizotto Jr., Edevar (MDPI AG, 2022-09)

[EN] Air valves are often crucial components in an air management strategy for pressurized water conveyance systems. However, the reliability of characteristic curves of air valves found in product catalogs is quite variable. ...
Transient phenomena during the emptying process of water in pressurized pipelines

Coronado Hernández, Óscar Enrique (Universitat Politècnica de València, 2020-04-04)

[ES] El análisis de los fenómenos transitorios durante las operaciones de llenado en conducciones de agua ha sido estudiado de manera detallada comparado con las maniobras de vaciado. En este último se encontró que no ...
