    El rendimiento de una turbina, está sujeto al comportamiento del flujo a través de las directrices del distribuidor y de los álabes del rodete. Para evitar que el flujo de agua procedente del embalse introduzca cuerpos ...
  • Numerical simulation of cavitation-erosion on a plane-convex hydrofoil using a homogeneous mixture assumption 

    Hidalgo, V.; Luo, Xianwu; Escaler Puigoriol, Francesc Xavier; Valencia, E.; Cando, E.; Yang, D. (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A better understanding of the cavitation-erosion mechanism is important to improve the prediction of the affected region under unsteady cavitation condition. For that, a new model has been proposed to estimate the microjet ...
