Investigations of plate-type windborne debris—Part II: Computed trajectories

In Part I, trajectories of plates, carried by strong winds, were studied experimentally by wind-tunnel and full-scale tests. The application is to windborne debris occurring in severe windstorms such as hurricanes. In this paper (Part II), a numerical model of square plate trajectories is described and compared with experimental data from Tachikawa, and that described in Part I. Generally, good to excellent agreement is found; lift forces induced by the Magnus effect were found to be significant in determining trajectories.
