  Title Maximization of granular outflow by oblique exits and by obstacles Type Journal Article
  Year 2009 Publication Physics Of Fluids Abbreviated Journal Phys. Fluids  
  Volume 21 Issue 3 Pages 3 pp  
  Keywords confined flow; granular flow  
  Abstract We investigate experimentally the intermittent discharge of a granular medium out of an exit at the bottom of a vertically shaken box. Changing the orientation of the bottom shows that there exists an angle (around 20 degrees-25 degrees with respect to the horizontal) at which the mean discharge rate increases up to a factor 1.9, as compared to the rate with horizontal bottom. Furthermore, adjusting the diameter and the distance of a cylindrical obstacle above the exit on the (horizontal) bottom, allows to optimize the mean rate of discharge up to 3.5 times the rate without obstacle.
