Collapse Dynamics and Runout of Dense Granular Materials in a Fluid: videos 3 and 4


Theses videos show the collapse of fixed width granular column:

- on the first, aspect ratio a=10, with water,

- on the second, aspect ratio a=7, in a more viscous fluid.

 

Grains diameter = 10-3 m, grains density = 2.6. The viscous fluid has a 1000 higher viscosity than water.

 

The color levels indicate the particles and fluid velocities (red for the higher velocities, blue for the lowest ones).
