| Outline of Final Research Achievements |
The flow fields in the tornado-like flow simulator with multi-fan and multi-vane were investigated by 3D PIV method. On the other hand, it was clalified that debris flying in Tornado formed debri cloud by the equilibrium of aerodynamic forces, centrifugal force and gravity in radius-height plane. Moreover, it was indicated that strength and scale of tornado flows could be estimated from their photo and movies by investigation of relation ships between charateristics of tornado flows and shapes of their funnel clouds and of their debris clouds.
