Numerical Simulations of Wind Turbine Wake Interactions by Using the Supercomputer Version RIAM-COMPACT

- An Application to Offshore Wind Farms -

Abstract

In this paper, the supercomputer version of RIAM-COMPACT is applied to an offshore wind farm. In calculations using a virtual offshore wind farm model, we found that when the wind enters from an oblique direction (15 degrees), there is no significant decrease in the wind speed entering the downstream wind turbines. Furthermore, in the case of a full-scale offshore wind farm, it was clearly shown that the trends in the measured data could be reproduced by periodically varying the wind direction within a horizontal cross section.
