2D CFD modeling of rapid water filling with air valves usign OpenFOAM

Aguirre-Mendoza, Andrés M.; Oyuela, Sebastián; Espinoza-Román, Héctor G.; Coronado-Hernández, Oscar E.; Fuertes-Miquel, Vicente S.; Paternina-Verona, Duban A. (MDPI AG, 2021-11)

[EN] The rapid filling process in pressurized pipelines has been extensively studied using mathematical models. On the other hand, the application of computational fluid dynamics models has emerged during the last decade, ...
Computational Determination of Air Valves Capacity Using CFD Techniques

García-Todolí, Salvador; Iglesias Rey, Pedro Luís; Mora Melia, Daniel; Martínez-Solano, F. Javier; Fuertes-Miquel, Vicente S. (MDPI AG, 2018-10)

[EN] The analysis of transient flow is necessary to design adequate protection systems that support the oscillations of pressure produced in the operation of motor elements and regulation. Air valves are generally used in ...
Desarrollo de una metodología de caracterización de válvulas de aire en admisión mediante técnicas computacionales

González Fuertes, Max José (Universitat Politècnica de València, 2018-04-11)

La operación de los sistemas de abastecimiento de agua implica procedimientos que pueden generan eventos hidráulicos dañinos para la infraestructura. Un claro ejemplo es el vaciado de tuberías que produce presiones negativas ...
Effect of a commercial air valve on the rapid filling of a single pipeline: a numerical and experimental analysis

Coronado-Hernández, Oscar E.; Besharat, Mohsen; Fuertes-Miquel, Vicente S.; Ramos, Helena M. (MDPI AG, 2019-08-31)

[EN] 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. ...
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 ...
Numerical modelling for analysing drainage in irregular profile pipes using OpenFOAM

Paternina-Verona, Duban A.; Coronado-Hernández, Oscar E.; Fuertes-Miquel, Vicente S. (Taylor & Francis, 2022-07-03)

[EN] Different methods of two-dimensional and three-dimensional numerical resolution models have been used to predict the air¿water interaction in pipe systems in the early twenty-first century, where reliable and adequate ...
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 a single pipe with water air interaction

Fuertes-Miquel, Vicente S.; Coronado-Hernández, Oscar Enrique; Iglesias Rey, Pedro Luís; Mora Melia, Daniel (Taylor & Francis, 2019)

[EN] Emptying pipelines can be critical in many water distribution networks because subatmospheric pressure troughs could cause considerable damage to the system due to the expansion of entrapped air. Researchers have given ...
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 ...
