Large Eddy Simulation of the transient cavitating vortical flow in the wake of a hydrofoil
(2021)
Text en actes de congrés
Accés obertThe Zwart mixture cavitation model and the Large Eddy Simulation (LES) turbulence model have been combined to simulate the transient cavitating flow in the wake of a hydrofoil. The hydrofoil is a 2D NACA0009 with a truncated ... -

Text en actes de congrés
Accés obertThis paper proposes an innovative control algorithm for Permanent Magnet Synchronous Machines (PMSMs), based on a Vector Current Control (VCC) strategy in order to operate in the Flux-Weakening (FW) zone and a Finite Element ... -
Numerical investigation of the effects of hydrofoil vibrations on the unsteady behavior of cavitation
(Institute of Physics (IOP), 2021)
Text en actes de congrés
Accés obertIn order to better understand the fluid-structure interaction (FSI) in hydraulic machines, this study aims to numerically investigate the flow around an oscillating hydrofoil with special attention on the effect of ... -
Measurement of the Influence of Sheet Cavitation on the Heat Generated in a Closed Loop Pumping System
(2021)
Comunicació de congrés
Accés restringit per política de l'editorialThe 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 ... -

(Institute of Physics (IOP), 2021)
Text en actes de congrés
Accés obertThe present study intends to investigate numerically the impact of: i) the fluid added mass, ii) the turbine rotational speed and iii) the variation of the runner blade bearing stiffness due to the turbine water head on ... -
Numerical modal analysis of a Kaplan turbine runner
(2020)
Comunicació de congrés
Accés obertThe aim of the research has been to investigate the change of dynamic behavior of a Kaplan turbine runner when submerged in still water. More specifically, the effects of the added mass on the modes of vibration have been ... -
Near-interface modeling in large-eddy simulation of two-phase turbulent flow
(2020)
Text en actes de congrés
Accés obertThe smallest hydrodynamic length scales in interfacial turbulent flow are located at the interface between phases/fluids as a result of two-way coupling phenomena. These interface-generated scales are, typically, several ... -
