Simulation of Turbulent Flow Inside and Above Wind Farms: Model Validation and Layout Effects

A recently-developed large-eddy simulation framework is validated and used to investigate turbulent flow within and above wind farms under neutral conditions. Two different layouts are considered, consisting of thirty wind turbines occupying the same total ...

Flow over Hills: A Large-Eddy Simulation of the Bolund Case

Jiannong Fang, Marc Parlange, Chad Higgins, Marc Diebold

Simulation of local atmospheric flows around complex topography is important for several applications in wind energy (short-term wind forecasting and turbine siting and control), local weather prediction in mountainous regions and avalanche risk assessment ...

Near-wake instability and sensitivity analysis of wind turbines immersed in the atmospheric boundary layer

Fernando Porté Agel, François Gallaire, Giacomo Valerio Iungo, Francesco Viola

In wind farms, the separation distance among wind turbines is mainly determined by the downstream recovery of wind turbine wakes, which affects in turn power production and fatigue loads of downstream turbines. Thus, the optimization of a wind farm relies ...

A robust fault detection and isolation filter for a horizontal axis variable speed wind turbine

Maryam Kamgarpour, Bratislav Svetozarevic

We develop a robust fault detection and isolation (FDI) technique in the presence of measurement noise and apply it to the horizontal axis variable speed wind turbine. In the first part, we provide a nonlinear model of the wind turbine in the form of diffe ...

Improving Remaining-Fatigue-Life Evaluation Using Data Interpretation

Ian Smith, Yves Sylvain Gilles Reuland, Romain Pasquier

This paper presents a methodology that improves fatigue-performance evaluations using model-based data interpretation. The accuracy of stress-range values is essential for quantifying fatigue damage. These values are usually predicted using physics-based m ...

Circulation patterns in open, wide and deep lacustrine embayments with different aspect ratios

David Andrew Barry, Ulrich Lemmin, Amir Mehdi Razmi

Numerical simulations were carried out to examine the effect of different horizontal aspect ratios on wind-induced circulation within open, wide and deep lacustrine embayments. Two adjacent embayments in Lake Geneva, Switzerland, located between Morges and ...

Hybrid probabilities and error-domain structural identification using ambient vibration monitoring

Ian Smith, Clotaire Michel, James-Alexandre Goulet

For the assessment of structural behaviour, many approaches are available to compare model predictions with measurements. However, few approaches include uncertainties along with dependencies associated with models and observations. In this paper, an error ...

Model falsification diagnosis and sensor placement for leak detection in pressurized pipe networks

Ian Smith, Sylvain Coutu, James-Alexandre Goulet

Pressurized pipe networks used for fresh-water distribution can take advantage of recent advances in sensing technologies and data-interpretation to evaluate their performance. In this paper, a leak-detection and a sensor placement methodology are proposed ...
