Five MegawattWind Turbine Power Output Improvements by Passive Flow Control Devices
(MDPI, 2017-06)
The effects of two types of flow control devices, vortex generators (VGs) and Gurney flaps (GFs), on the power output performance of a multi-megawatt horizontal axis wind turbine is presented. To that end, an improved blade ...
A novel procedure to determine the cohesive law In DCB tests
(Elsevier, 2017-11-10)
A novel method is presented for the determination of mode I cohesive law for the characterization of delamination in unidirectional carbon fiber reinforced polymer laminates. The energy release rate as a function of the ...
Analysis of the DCB test of angle-ply laminates including residual stresses
(Elsevier, 2017-03-14)
[ES] Se propone un nuevo método para obtener la tasa de liberación de energía mediante la prueba de doble viga en voladizo para laminados de capas angulares. Se estudian dos secuencias diferentes, simétrica y antisimétrica. ...
Equivalent Energy Release Rate And Crack Stability In The End Notched Flexure With Inserted Roller Mixed Mode I/II Test
(Elsevier, 2017-02)
The crack propagation performance of the End Notched Flexure with inserted roller test is analyzed. An equivalent energy release rate is proposed taking into account the interaction of the modes I and II, based on the ...
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. ...
