Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
Gurney Flap Implementation on a DU91W250 Airfoil
(MDPI, 2018-11-06)
Abstract
The increasing capability of Wind Turbine (WT) based power generation systems has derived in an increment of the WT rotor diameter, i.e., longer rotor blades. This results in an increase of the electrical power ...
Sustainable Alternative of Structural Concrete Retaining Tanks
(Emerald Publishing, 2018-05)
The environmental footprint of the construction industry requires the quantification of new developments to appraise their sustainable contribution. Recent developments in relation to the merging of steel fibre reinforced ...
Study of historical developments in the use of fire resistant steels
(Taylor&Francis, 2014-10-29)
This paper presents a review of the most relevant articles on fire-resistant (FR) steels, as part of a research project at the University of the Basque Country (UPV/EHU) on the FR properties of steelstructures. An important ...
Assessment of the influence of façade location and orientation in indoor environment of double-skin building envelopes with perforated metal sheets
(Elsevier, 2019-08-03)
Double-skin perforated sheet façades, enclosures consisting of perforated screens, air chambers and glass/wall sheets, are features of modern building design that are winning greater acceptance. A detailed analysis of their ...
Skid resistance prediction for new two-lane roads
(ICE Publishing, 2019-10)
[EN]Skid resistance is a vital issue in pavement management, mainly in relation to road safety; hence, road agencies must assure a minimum friction level of their road networks. The regional government of Biscay (Spain) ...

(Elsevier, 2019-10-17)
The grinding process is continuously adapting to industrial requirements. New advanced materials have beendeveloped, which have been ground. In this regard, new abrasive grains have emerged to respond to the demands of ...
Failure-Analysis Based Redesign of Furnace Conveyor System Components: A Case Study
(MDPI, 2019-08)
Any manufacturing equipment designed from scratch requires a detailed follow-up of the performance for the first units placed in service during the production ramp-up, so that lessons learned are immediately implemented ...
Chatter avoidance in the milling of thin floors with bull-nose end mills: Model and stability diagrams
(Elsevier, 2011-01)
The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the ...
