Activities
In general, rapid granular flows are characterized by shock waves and high Mach number flows. This is due to the inelastic collisions of the granular material in the granular flow. These collisions reduce the relative velocities of the granular material, which in turn decrease the local granular temperature, defined as the variance of the local velocity distribution. The dissipation of temperature causes a reduction of the sound speed within the granular flow, and as a result, as the flow progresses the mean particle velocity exceeds the speed of sound within the granular flow. Essentially the flow becomes supersonic. Therefore just as in elastic gases, as the flow encounters an obstacle there is a tendency for shocks to form within the flow. In this research effort, the interactions of shock waves within rapid granular flows are examined with reference to interactions within elastic gases.
