A Large Eddy Simulation Study for upstream wind energy conditioning

Varun Sharma, Marc Parlange, Marc Calaf Bracons

The wind energy industry is increasingly focusing on optimal power extraction strategies based on layout design of wind farms and yaw alignment algorithms. Recent field studies by Mikkelsen et al. (Wind Energy, 2013) have explored the possibility of using ...

Total Light Transmittance of Glass Fiber-Reinforced Polymer Laminates for Multifunctional Load-Bearing Structures

Thomas Keller, Andreas Schueler, Julia De Castro San Roman Fest, Carlos Pascual Agullo

Glass fiber-reinforced polymer (GFRP) materials are increasingly used in building construction for the design of multifunctional structures. These composite materials allow the integration of structural functions, building physics functions (mainly thermal ...

Fatigue life prediction of wind turbine blade composite materials

Anastasios Vassilopoulos

Fatigue life prediction of wind turbine rotor blades is a very challenging task, as blade failure is led by different failure types that act synergistically. Inherent defects like wrinkles, fiber misalignments and voids, that can be introduced during fabri ...

Evolution of the Aerodynamic Stability of an Oscillating Annular Compressor Cascade with Inlet Reverse Flow Condition Variations

Peter Ott, Virginie Anne Chenaux

While the advancement of computing hardware now enables accurate predictions of flutter and forced response at normal flow conditions during the compressor design phase, aeroelastic computations at off-design or reverse flow conditions remain a challenging ...

Contribution to shear wrinkling of GFRP webs in cell-core sandwiches

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Behzad Dehghan Manshadi

Glass-fiber-reinforced polymer (GFRP) cell-core sandwiches are composed of outer GFRP face sheets, a foam core, and a grid of GFRP webs integrated into the core to reinforce the shear load capacity. One of the critical failure modes of cell-core sandwich s ...

Models of wind-turbine main-shaft bearings for the development of specific lightning protection systems

Mario Paolone

One of the main causes of damages for wind-turbine power plants is lightning. Direct and indirect events, indeed, can produce damages and malfunctions of electrical and mechanical components. Concerning mechanical components, blades and bearings are the mo ...

Shear wrinkling of GFRP webs in cell-core sanwiches

Thomas Keller, Anastasios Vassilopoulos, Behzad Dehghan Manshadi

Glass fiber-reinforced (GFRP) cell-core sandwich structures are increasingly used in bridge deck and roof construction. GFRP cell-core sandwiches are composed of the outer GFRP face sheets, a foam core and a grid of GFRP webs integrated into the core in or ...

Improving the Turbulence Coupling between High Resolution Numerical Weather Prediction Models and Lagrangian Particle Dispersion Models

Balazs Szintai

For the modelling of the transport and diffusion of atmospheric pollutants during accidental releases, sophisticated emergency response systems are used. These modelling systems usually consist of three main parts. The atmospheric flow conditions can be si ...

Environmental effects on fatigue behavior of adhesively-bonded pultruded structural joints

Thomas Keller, Anastasios Vassilopoulos, Ye Zhang

The fatigue response of adhesively-bonded pultruded GFRP double-lap joints has been investigated under different environmental conditions. Tests were performed at -35 °C, 23 °C and 40 °C. A fourth set of fatigue data was collected from tests on preconditio ...
