Experimental Investigation of the Cavitation Effects on the Heat Generation in a Closed Loop Pumping System
(2018)
Conference report
Open AccessA series of tests were carried out in the cavitation tunnel of the Laboratory for Water and Turbine Machines of the University of Ljubljana in order to investigate the effects of cavitation in the water heating process of ... -
Numerical simulation of the micro-jet velocity and cavitation-erosion on an axisymmetric nozzle
(2018)
Conference report
Open AccessThe present study deals with the numerical study of the micro-jet velocity and the cavitation - erosion on an axisymmetric nozzle, which presents high ow unsteadiness and aggressiveness. The proposed model is based on ... -
Assessment of remote cavitation detection methods with flow visualization in a full scale francis turbine
(2018)
Conference report
Open AccessThis paper describes the experimental investigations carried out in the Francis turbine at Svorka power plant operated by Statkraft in Norway. The unit, with a head of 260 m, can deliver a maximum output load of 25 MW. The ... -
Sensitivity analysis of zwart-gerber-belamri model parameters on the numerical simulation of francis runner cavitation
(2018)
Conference report
Open AccessA series of numerical simulations of the 3D cavitation development in the GAMM Francis turbine runner were carried out with the Zwart-Gerber -Belamri (ZGB) two-phase model available in ANSYS ¿ CFX v16.2. The aim of the ... -
Driving mechanisms and streamwise homogeneity in molecular dynamics simulations of nanochannel flows
(2018-01-12)
Article
Open AccessIn molecular dynamics simulations, nanochannel flows are usually driven by a constant force, that aims to represent a pressure difference between inlet and outlet, and periodic boundary conditions are applied in the ... -

Pressure retarded osmosis thermosyphon
(2018-05-18)
Article
Restricted access - publisher's policyThe basis of a novel method for passive solar water heating homologous to the thermosyphon but driven by induced salinity which circulates a fluid without the necessity of a mechanical pump and with inverse natural convection ... -
Real-time seismic data from the bottom sea
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-04-08)
Article
Open AccessAn anchored marine seismometer, acquiring real-time seismic data, has been built and tested. The system consists of an underwater seismometer, a surface buoy, and a mooring line that connects them. Inductive communication ... -
Transmission of high frequency vibrations in rotating systems. Application to cavitation detection in hydraulic turbines
(Multidisciplinary Digital Publishing Institute, 2018-03-16)
Article
Open AccessOne of the main causes of damage in hydraulic turbines is cavitation. While not all cavitation appearing in a turbine is of a destructive type, erosive cavitation can severely affect the structure, thus increasing maintenance ... -
Sensor-based optimized control of the full load instability in large hydraulic turbines
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-03-30)
Article
Open AccessHydropower plants are of paramount importance for the integration of intermittent renewable energy sources in the power grid. In order to match the energy generated and consumed, Large hydraulic turbines have to work under ... -
GPR clutter amplitude processing to detect shallow geological targets
(2018-01-01)
Article
Open AccessThe analysis of clutter in A-scans produced by energy randomly scattered in some specific geological structures, provides information about changes in the shallow sedimentary geology. The A-scans are composed by the coherent ... -
