Sensitivity analysis of the efficiency of a parabolic-trough solar collector
(2016-09-09)
The text presented below analyses the variation of the performance of a parabolic trough solar collector, when some of the parameters that govern its operation vary due to dirty mirror, degradation etc.
In order to reach ...
Parametric Modellig and Fatigue Damage Assessment of Offshore Wind Turbine Support Structures
(2016-12-21)
Offshore wind turbines suffer a number of environmental loads which damage their support structure and decrease their lifetime. These forces are produced by the wind, waves and currents and they damage the monopile cyclically. ...
Reserve Requirement Impacts of Microgrid Integration of Wind, Solar, and Ocean Wave Power Generation
(2016-12-21)
The ocean wave energy is a free and abundant resource which has led to exploring new methods to take advantage of the energy in an efficient and profitable way. The wave energy harnessing techniques are not as mature as ...
S-CO2 for efficient power generation with energy storage
(2016-12-21)
Supercritical CO2 (s-CO2) power cycle has gained interest for concentrating solar power (CSP) application in the last decade to overcome the current low efficiency and high costs of the plants. This cycle is a potential ...
A thermogravimetric and kinetic study on devolatization of woody biomass
(2016-12-21)
Biomass is a promising energy resource for a more sustainable global energy outlook. Thermochemical conversion of biomass is a very attractive and important technology for energy generation and production of value-added ...
Aircraft performance with onboard water condensed from engine core exhaust for contrail prevention
(2016-12-21)
Aviation industry has experienced a constant growth over the last decades, and forecasts suggest that this trend will continue. This is not attractive from an environmental point of view due to the increasing contribution ...
Analysis of the energy savings gained by protective glazing on stained single-glass windows at Uppsala Cathedral
(2016-12-21)
Most European stained glass windows have no protection to reduce the damage due to environmental exposure, and this is the case of the great gothic windows in the Uppsala Cathedral. Currently, the implementation of protective ...
Aeroacoustic analysis of various noise sources: comparison of jet nozzles on BeamformX
(2016-12-21)
This work revolves around the research in aeroacoustics: first an introduction to the concepts of
noise, aeroacoustics and the importance of noise monitoring, identification and control will be
presented.
After that, ...
Design of the test cycles for a wind turbine gearbox
(2016-12-21)
The premise of this project work has been defining the test cycles for the gearbox of a wind turbine that will be tested in the just mentioned nacelle test rig. As it does not exist a standard methodology to test a wind ...
