Study of the state a Francis turbine
(Politechnika Gdanska, Wydzial Oceanotechniki i Okretownictwa, 2013-04-01)
This paper presents a methodology to evaluate the technical state of a Francis turbine by shaft rotor dynamic simulation. There are several rotor dynamic criteria that define the technical state of a turbo-machine. To feed ...
Anatomical Variant in Middle Turbinate: Concha Bullosa, Finding on Cone Beam Computerized Tomography
(Universidad de Costa Rica, 2023)
The nasal turbinates, also called nasal shells, are attached to the lateral and/or superior walls of the nostril and can present several anatomical variations. Thus, we can mention the concha bullosa, the ...
Shrouded wind turbine performance in yawed turbulent flow conditions
(2021)
Wind turbines represent a growing energy source worldwide. In many cases, operating in turbulent and changing wind
direction spots. In this work, we use a wind tunnel to analyse the effect of the turbulence in a wind ...

LPV wind turbine control with anti-windup features covering the complete wind speed range
(Institute of Electrical and Electronics Engineers, 2014-03)
This paper addresses the control of a variable-speed variable-pitch wind turbine in the whole wind speed range. To this end, a linear parameter varying anti-windup (AW) controller is proposed as part of a control structure ...
Improving the efficiency of a Savonius wind turbine by designing a set of deflector plates with a metamodel-based optimization approach
(Pergamon-Elsevier Science Ltd, 2019-07)
Savonius wind turbines are the most suitable devices used in urban areas to produce electrical power. This is due to their simplicity, ease of maintenance, and acceptable power output with a low speed and highly variable ...
LPV-based active power control of wind turbines covering the complete wind speed range
(Pergamon-Elsevier Science Ltd, 2016-12)
This paper focuses on the active power control of wind turbines. Modern grid codes increasingly demand active power control in order to guarantee utility grid stability under high wind energy penetration. Active power ...
