    The so-called hydrodynamic heat generators are claimed as high efficiency heating devices, avoiding scaling by warming liquids without transfer surface with the help of cavitation effects. However, neither the mechanisms ...
  • Effect of land cover and climate changes on rainfall-induced landslides: regional-scale modelling in the Val d’Aran (Pyrenees, Spain) 

    Hurlimann Ziegler, Marcel; Medina Iglesias, Vicente César de; Lloret Morancho, Antonio; Vaunat, Jean; Puig i Polo, Càrol; Moya Sánchez, José (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2021)
    Conference report
    Open Access
    The analysis of the impacts of future environmental changes on rainfall-induced landslides is of great importance. Recent studies have shown that these changes will affect the frequency and magnitude of shallow slides and ...
  • Effect of the actuation on the boundary layer of an airfoil at moderate reynolds number 

    Lehmkuhl, Oriol; Rodríguez Pérez, Ivette María; Borrell Pol, Ricard (Springer, 2020)
    Conference report
    Restricted access - publisher's policy
    Synthetic (zero net mass flux) jets are an active flow control technique to manipulate the flow field in wall-bounded and free-shear flows. The fluid necessary to actuate on the boundary layer is intermittently injected ...
