Two-Dimensional Slope#
1. Project Description#
The objective of this project is to reproduce the wind flow properties over the two-dimensional slope, as measured in wind tunnel by [1]. The domain of interest is at resolution level “lvl4” of the digital wind tunnel. One convective time scale is defined as \(CTS = H / U_H\).
