An implicit formulation for calculating final conditions in drainage maneuvers in pressurized water installations

Coronado-Hernández, Oscar E.; Bonilla-Correa, Dalia M.; Lovo, Aldo; Fuertes-Miquel, Vicente S.; Gatica, Gustavo; Linfati, Rodrigo; Coronado-Hernández, Jairo R. (MDPI AG, 2022-11)

[EN] Emptying processes are typical maneuvers that should be performed by water distribution companies for operation purposes. These processes involve a complex numerical analysis, since a set of algebraic and ordinary ...
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, ...
Backflow air and pressure analysis in emptying a pipeline containing an entrapped air pocket

Besharat, Mohsen; Coronado-Hernández, Oscar Enrique; Fuertes-Miquel, Vicente S.; Viseu, Maria Teresa; Ramos, Helena M. (Taylor & Francis, 2018-11-14)

[EN] 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. ...
Computational fluid dynamics for sub-atmospheric pressure analysis in pipe drainage

Besharat, Mohsen; Coronado-Hernández, Oscar Enrique; Fuertes-Miquel, Vicente S.; Viseu, Maria Teresa; Ramos, Helena M. (Taylor & Francis, 2019-08-06)

[EN] 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 ...
Different Experimental and Numerical Models to Analyse Emptying Processes in Pressurised Pipes with Trapped Air

Paternina-Verona, Duban A.; Coronado-Hernández, Oscar E.; Espinoza-Román, Héctor G.; Fuertes-Miquel, Vicente S.; Ramos, Helena M. (MDPI AG, 2023-07)

[EN] In hydraulic engineering, some researchers have developed different mathematical and numerical tools for a better understanding of the physical interaction between water flow in pipes with trapped air during emptying ...
Two-dimensional simulation of emptying manoeuvres in water pipelines with admitted air

Paternina-Verona, Duban A.; Flórez-Acero, Luis C.; Coronado-Hernández, Oscar E.; Espinoza-Román, Héctor G.; Fuertes-Miquel, Vicente S.; Ramos, Helena M. (Taylor & Francis, 2023-05-09)

[EN] This study examines the impact of sub-atmospheric pressures in water pipelines during emptying manoeuvres with air admitted. Previous research has looked at this issue but has not studied it in detail. This research ...
