要約

The radial and tangential velocity components of the disturbed flow in a pipe are measured with PIV. The tracer particles illuminated with a light sheet normal to the pipe axis are imaged onto the recording camera through an endoscope. Swirl and vortical structures downstream of a 90° out-of-plane double bend can be measured. The results indicate that the flow immediately downstream of the bend is highly unsteady, and it must be concluded that the value of the usual time-averaged representations of this flow is questionable.
