Analysis of hydraulic transients during pipeline filling processes with air valves in large-scale installations

Romero, Guillermo; Fuertes-Miquel, Vicente S.; Coronado-Hernández, Óscar E.; Ponz-Carcelén, Román; Biel-Sanchis, Francisco (Taylor & Francis, 2020-08-04)

[EN] During the filling process in pressurized hydraulic systems, sudden pressure changes generated inside the pipes can cause significant damage. To avoid these excessive overpressures, air valves should be installed to ...
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 ...
Enhancing Friction Models for Starting Up Water Installations Containing Trapped Air

Fuertes-Miquel, Vicente S.; Arrieta-Pastrana, Alfonso; Coronado-Hernández, Oscar E. (MDPI AG, 2023)

[EN] Starting up water installations is typically a task that falls within the purview of water utility companies. These operations involve the presence of two separate fluids (water and air) that can be analyzed in terms ...
Modelo de llenado de grandes conducciones

Romero Sedó, Antonio Manuel; Arrué, Paloma; García-Serra, Jorge; Espert, Vicent B.; Biel, F. (Universitat Politècnica de València, 2018-10-30)

[EN] The filling of pipelines must be made in conditions of maximum safety, since it is a delicate operation that can generate important system overpressures. The need, therefore, arises to design a filling protocol for ...
Real-Time Analysis and Digital Twin Modeling for CFD-Based Air Valve Control During Filling Procedures

Paternina-Verona, Duban A.; Coronado-Hernández, Oscar E.; Pérez-Sánchez, Modesto; Ramos, Helena M. (MDPI AG, 2024-10-22)

[EN] Air exchange in pressurized water pipelines is an essential but complex aspect of pipeline modeling and operation. Implementing effective air management strategies can yield numerous benefits, enhancing the system¿s ...
Transient Phenomena Generated in Emptying Operations in Large-Scale Hydraulic Pipelines

Romero, Guillermo; Fuertes-Miquel, Vicente S.; Coronado-Hernández, Óscar E.; Ponz-Carcelén, Román; Biel Sanchis, Francisco (MDPI AG, 2020-08)

[EN] Air pockets generated during emptying operations in pressurized hydraulic systems cause significant pressure drops inside pipes. To avoid these sudden pressure changes, one of the most widely used methods involves the ...
