A Numerical Study of Granular Surge Flow through a Row of Baffles.

A numerical study that utilizes three-dimensional discrete element method was undertaken to investigate the impact process and the dynamic interaction between granular surge flow and baffles. In the numerical analyses, the granular flow medium and the baffles were modelled as frictional spherical discrete elements and rigid square objects respectively. The location, velocity and forces acting on the individual discrete elements during the impact and interaction process were captured and recorded in the analyses. A detailed assessment of the numerical output data indicates that a single row of baffles is effective in reducing the kinetic energy and discharge of the granular surge flow
