Measurement of the characteristics of a rapid dry granular flow

This study investigated granular flows in an inclined channel. The aim was to analyze the characteristics of flow and their impact loads on a slightly sloping structure such as a snow shed. The physical properties were measured. The height of the flow was determined over time using a laser beam and a camera, identifying different flow regimes. Using the PIV method, we determined the flow's velocity profile, the temperature profile and the bulk density of the flow by a new method based on image processing and integrating a calibration law. Finally, the spatiotemporal changes in impact pressures were obtained for different load sensor positions after the change in slope.
