| Description |
This paper investigates the formation of hydraulic jumps in the open channel flow of dry, cohesionless granular materials. The experimental observations include the identification of several types of jump and several types of downstream flow. The relation between the depth ratio across the jump and the Froude number is similar to that observed in the open channel flow of liquid. However, the ratio h_2/h_1 in the granular material case is larger by a factor of between 1.2 and 1.5 Analysis of this factor indicates that it is caused by a 10 to 20% reduction in the solid fraction below its critical value in the highly sheared supercritical flow upstream of the jump.
