Analytical modelling of wind speed deficit in large offshore wind forms

The proposed model for the wind speed deficit in wind forms is analytical and encompasses both small wind forms and wind forms extending over large areas. As is often the need for offshore wind forms, the model handles a regular array geometry with straight rows of wind turbines and equidistant spacing between units in each row and equidistant spacing between rows. Firstly, the case with the flow direction being parallel to rows in a rectangular geometry is considered by defining three flow regimes. Secondly, when the flow is not in line with the main rows, solutions are suggested for the patterns of wind turbine units corresponding to each wind direction. The presentation is an outline of a model complex that will be adjusted and calibrated with measurements in the near future. Copyright (c) 2006 John Wiley & Sons, Ltd.
