Modelling and adaptive parameter estimation for a piezoelectric cantilever beam
(2022)
Article
Open AccessThis paper proposes a new adaptive estimation approach to online estimate the model parameters of a piezoelectric cantilever beam. The beam behavior is firstly modeled using partial differential equations (PDE) considering ... -
Shutdown idling performance of the nuclear main coolant pump under station blackout accident: An optimization study
(SAGE publishing, 2022-05-25)
Article
Restricted access - publisher's policyLead-cooled fast reactor (LFR) is an important reactor type of the Generation IV nuclear energy, and the main coolant pump (MCP) is the only and most critical power equipment in primary circuit of LFR. The shutdown idling ... -
Dynamic response analysis of a reduced scale Kaplan turbine model operating in propeller mode
(IOP Publishing, 2022)
Conference report
Open AccessIn the frame of the AFC4Hydro H2020 research project, an extensive measurement campaign has been carried out on a reduced scale Kaplan turbine model at the Vattenfall Research and Development facility in Älvkarleby, Sweden. ... -
PZT actuators as on-board instruments to reduce vibrations and strains in submerged structures
(IOP Publishing, 2022)
Conference report
Open AccessThis paper presents the design and evaluation of an active control system to reduce vibrations and strains of submerged structures. For that, a metallic disk mounted in a test rig has been equipped with on-board waterproof ... -
Experimental and numerical investigation on the influence of a large crack on the modal behaviour of a Kaplan turbine blade
(Elsevier, 2020-01-01)
Article
Open AccessA large crack was discovered on one blade of a Kaplan turbine prototype after the inspection of the machine. In order to know the origin of the crack, a failure analysis was previously carried out (Zhang et al., 2019). To ... -
Analysis of the mode shapes of Kaplan runners
(Multidisciplinary Digital Publishing Institute, 2022-07-02)
Article
Open AccessTo prevent lifetime shortening and premature failure in turbine runners, it is of paramount importance to analyse and understand its dynamic response and determine the factors that affect it. In this paper, the dynamic ... -
On the use of vibrational hill charts for improved condition monitoring and diagnosis of hydraulic turbines
(2022-01-22)
Article
Open AccessTo cope with the intermittent power supply of the new renewable energies and demand fluctuations, Francis turbines are required to operate more and more in an extended operating range, far away from the design point. With ... -
Experimental investigation on the dynamic response of Pelton runners
(Institute of Physics (IOP), 2019)
Conference report
Open AccessAn effective condition monitoring is essential to increase the availability of Pelton turbines and to avoid unexpected damage. The main challenge consists in determining the deformations and the stresses in the runner while ... -
On the exctitation of a submerged disk-like structure with RSI patterns
(2015)
Conference report
Restricted access - confidentiality agreementDetermining the dynamic response of submerged and confined disk-like structures is of interest in the hydraulic turbines field. Disks present similar dynamic characteristics than hydraulic turbine runners, especially in ... -
Transient Analysis of Pelton Turbine Prototypes
(2021)
Conference report
Open AccessOne of the most critical operating conditions in hydraulic turbines is the start-up transient. This may be characterized by the presence of several resonances, which increase the vibration and stress levels on the runners. ... -
Failure investigation of a solar tracker due to wind-induced torsional galloping
(Elsevier, 2022-05-01)
Article
Open AccessSolar power installations are increasing every year due to the decarbonization policy established around the world. Photovoltaic (PV) systems and specifically one-axis solar trackers are the most used type of installations ... -
Prediction of cavitation erosion with different erosion risk indicators
(2022-02)
Article
Open AccessThis present work devoted to simulate the unsteady cavitating flow around a hydrofoil and assess its erosion power predicted by different erosion risk indicators. For that, the behavior of unsteady cloud cavity is numerically ...
