    • Numerical study of the fluid-structure interaction in the diffuser passage of a centrifugal pump 

      Fontanals García, Alfred; Guardo Zabaleta, Alfredo de Jesús; Coussirat Núñez, Miguel Gustavo; Egusquiza Estévez, Eduard (Centro Internacional de Métodos Numéricos en Ingeniería (CIMNE), 2011)
      Text en actes de congrés
      Accés obert
      Reliable design of turbomachinery is a complex task. In order to gain overall efficiency in the machine performance, designers may have to reduce the gap between the impeller and the diffuser, forcing them to be as closely ...

    • Optimización de un banco de ensayos de cavitación mediante fluidodinámica computacional 

      Moll, Flavio; Manuele, Diego; Coussirat Núñez, Miguel Gustavo; Cappa, E. Franco; Gandolfo, Ernesto; Guardo Zabaleta, Alfredo de Jesús; Fontanals García, Alfred (2012)
      Article
      Accés obert
      Los flujos cavitantes se corresponden a una estructura bifásica (líquido-vapor) cuando la presión del líquido disminuye hasta su presión de vapor, pv. La aparición y el posterior colapso de cavidades de vapor cerca de ...

    • Prediction of the characteristic pressure pulsations in a reversible pump-turbine 

      Fontanals García, Alfred; Guardo Zabaleta, Alfredo de Jesús; Coussirat Núñez, Miguel Gustavo; Moll, Flavio; Egusquiza Estévez, Eduard; Martínez, Germán (2023-11)
      Article
      Accés obert
      Reversible Pump- Turbine turbomachines are frequently used in peaking load hydroelectrical power plants. These plants contribute to satisfy the energy demand during peak load periods. Its dynamic behaviour is influenced ...

    • Simulation of hot stamping processes 

      Riera Colom, María Dolores; Coussirat Núñez, Miguel Gustavo; Guardo Zabaleta, Alfredo de Jesús; Valls, I; Casellas Padró, Daniel (Grips' Media Gmbh, 2008)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Hot stamping is a thermo-mechanical technique that enables to give to a metallic blank the desired geometry and properties in a single step, where deformation at high temperature, phase transformations and heat transfer ...

    • Study of available turbulence and cavitation models to reproduce flow patterns in confined flows 

      Coussirat Núñez, Miguel Gustavo; Moll, Flavio; Cappa, E. Franco; Fontanals García, Alfred (2016-09)
      Article
      Accés restringit per política de l'editorial
      Cavitating flow in nozzles is a complex flow which implies a highly turbulent two-phase one. An accurate simulation which improves some numerical results found in the literature was achieved by means of an extensive ...
