Abstract

The coupled DEM-LBM technique is employed to simulate the leakage-soil interaction due to a leaking pipe. By adopting various particle surface energy values, the mechanical effect of soil cohesion is explored. It is found out that the orifice pressure drops with time after fluidisation occurs. And a stronger adhesion force leads to a slower decrease. In addition, the cavity size at a given time linearly decreases with the increase in the adhesion force between particles.
