Bolund Island#
1. Project Description#
The objective of this project is to reproduce the wind flow properties over the Bolund Island, as measured on-site by [1]. The domain of interest is at resolution level “lvl4” of the digital wind tunnel. One convective time scale is defined as \(CTS = H / U_H\), where \(H =\) 12 meters is the nominal height of the island.
