    • 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, Óscar Enrique; Espinoza Román, Héctor Gabriel; Fuertes Miquel, Vicente S. (Cartagena de Indias, 2021-09-15)
      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, fill, ...

    • Assessment of Steady and Unsteady Friction Models in the Draining Processes of Hydraulic Installations 

      Coronado Hernández, Óscar Enrique; Derpich, Ivan; Fuertes Miquel, Vicente S.; Coronado Hernández, Jairo Rafael; Gatica, Gustavo (Cartagena de Indias, 2021-07-08)
      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 laminar ...

    • Experimental and numerical analysis of a water emptying pipeline using different air valves 

      Coronado Hernández, Óscar Enrique; Fuertes Miquel, Vicente S.; Besharat M.; Ramos, H.M. (MDPI AG, 2017)
      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, 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 ...

    • Three-dimensional simulation of transient flows during the emptying of pipes with entrapped air 

      Paternina-Verona, Duban A; Coronado-Hernández, Oscar E; Aguirre-Mendoza, Andres M.; Espinoza-Román, Héctor G; Fuertes-Miquel, Vicente S (Cartagena de IndiasCampus Tecnológico, 2023-04-01)
      Two-and three-dimensional analyses of transient flows considering the air-water interaction have been a challenge for researchers due to the complexity in the numerical resolution of the multiphase during emptying in ...
