    • Rapid Filling Analysis with an Entrapped Air Pocket in Water Pipelines Using a 3D CFD Model 

      Paternina-Verona, Duban A.; Coronado-Hernández, Oscar E; Espinoza-Román, Héctor G; Fuertes-Miquel, Vicente S; Ramos, Helena M (Cartagena de Indias, 2023-02-21)
      A filling operation generates continuous changes over the shape of an air–water interface, which can be captured using a 3D CFD model. This research analyses the influence of different hydro-pneumatic tank pressures and ...

    • Three-dimensional analysis of air-admission orifices in pipelines during hydraulic drainage events 

      Paternina-Verona, Duban A.; Coronado-Hernández, Oscar E.; Espinoza-Román, Héctor G.; Besharat, Mohsen; Fuertes-Miquel, Vicente S; Ramos, Helena M (Cartagena de Indias, 2022-11-07)
      Air valves operate as protection devices in pipelines during drainage processes in order to mitigate vacuum pressures and control the transient flows. Currently, different authors have proposed one-dimensional models to ...
