Abstract
The mean trajectory of flying plate-like debris in tornado-like flow was investigated by 6DOF motion simulation of 3-D debris included flow field obtained by LES numerical fluid analysis. Moreover, the flying behavior of debris in tornado-like flow was explained by equilibrium condition of forces.
As the results of this study, it was clarified that the mean trajectory of debris in tornado-like flow was controlled by Tachikawa number defined by maximum tangent wind speed, and the relation between radius component of aerodynamic force and centrifugal force made a debri cloud.
