On the use of thermal conductive focusing for solar concentration enhancement
(2016-10)
Article.
Accés obert
Article.
Accés obert
We discuss the possibility for solar concentration enhancement via conductive heat transport. Here, we are concerned, as in orthodox approaches, about maximizing the solar concentration to obtain the highest receiver ...

Operating conditions leading to crack propagation in turbine blades of tidal barrages. Influence of head and operating mode
(Elsevier, 2020-01)
Article.
Accés obert
Article.
Accés obert
Tidal energy systems and specifically tidal barrages are renewable energy systems, that use the potential energy of tides to produce electricity. Actually, there are few tidal power stations operating, although recent ...
The Extractable hydrokinetic power from an oscillating membrane-based harvester
(Elsevier, 2019-01-22)
Article.
Accés obert
Article.
Accés obert
The extractable hydrokinetic power from an oscillating membrane in standing motion and induced by a water flow and its possible significance with regard energy harvesting is discussed. The main attractiveness of such an ...
Simulation model to find the best comfort, energy and cost scenarios for building refurbishment

Article.
Accés restringit per política de l'editorial
This article proposes a methodology to assess building behaviour, whilst taking its life cycle into account. Understanding of the system can be obtained by combining well-known energy consumption calculation engines (TRNSYS) ...
Numerical analysis of the influence of design parameters on the efficiency of an OWC axial impulse turbine for wave energy conversion
(2019-03-12)
Article.
Accés obert
Article.
Accés obert
Oscillating water column (OWC) axial impulse turbines permit the conversion of wave energy into electrical power. Unlike other hydropower units with a mature and well established technology, such turbines have been recently ...
On the use of ensemble averaging techniques to accelerate the Uncertainty Quantification of CFD predictions in wind engineering
(2022-09)
Article.
Accés obert
Article.
Accés obert
In this work we focus on reducing the wall clock time required to compute statistical estimators of highly chaotic incompressible flows on high performance computing systems. Our approach consists of replacing a single ...
Ocean salt basins energy harvesting
(2020-04-02)
Article.
Accés obert
Article.
Accés obert
In this work, the potential of harvesting energy from ocean salt basins is discussed. These deep ocean depressions which host thick salts deposits whose salinities could be up to 5-10 times higher than normal seawater open ...
Validation of the multi-objective structural optimisation of a composite turbine blade
(2018-11-15)
Article.
Accés obert
Article.
Accés obert
Structural optimisation of a wind turbine blade is presented in this work. The optimisation was performed using a multi-objective genetic algorithm and finite element modelling to determine the optimal structural design ...
