CFD Modeling of the wake interactions of two wind turbines on a Gaussian hill
One part of the solution to the problem of climate change is the use of wind energy for electricity generation. Onshore wind farms usually consist of a number of horizontal axis wind turbines closely spaced in clusters and they are often sited on complex terrain. Various models have been developed in the past to estimate the wake effects and optimize the siting of a wind farm, but they were mai...
متن کاملCFD Wake Modelling with a BEM Wind Turbine Sub-Model
Modelling of wind farms using computational fluid dynamics (CFD) resolving the flow field around each wind turbine’s blades on a moving computational grid is still too costly and time consuming in terms of computational capacity and effort. One strategy is to use sub-models for the wind turbines, and sub-grid models for turbulence production and dissipation to model the turbulent viscosity accu...
متن کاملA new strategy for controlling wind turbines against sensor faults and wake effects to harvest more electrical energy
This paper describes a new method for harvesting maximum electrical energy in wind farms. In proposing technique, the stochastic process principles are applied for detecting fault measurements of sensors. On the other hand, the wind farm is modeled by using fuzzy concept. Thereby the turbines are controlled against continuous changes in speed, direction and eddy currents of the blowing wind. To...
متن کاملAssessment of low-order theories for analysis and design of shrouded wind turbines using CFD
The use of a shroud around the rotor of a wind turbine has been known to augment the airflow through the rotor plane and hence result in improved performance. This work uses Computational Fluid Dynamics (CFD) to assess the validity of several simple theories which attempt to extend Betz theory to shrouded turbines. Two CFD models are employed and compared to predictions of previously published ...
متن کاملIndustrial wind turbines and adverse health effects.
INTRODUCTION Some people living in the environs of industrial wind turbines (IWTs) report experiencing adverse health and socioeconomic effects. This review considers the hypothesis that annoyance from audible IWTs is the cause of these adverse health effects. METHODS We searched PubMed and Google Scholar for articles published since 2000 that included the terms "wind turbine health," "wind t...
