VOF and DPM
 
Dear friends,

I am trying to model the flow of a solid particles through open channel (with water/air). To simulate the fluid flow I am using VOF model. For modeling solid inclusions I am using DPM. This small glass particles (10-200 um) have lower density than water and flowing up to the free surface. Theoretically they should stay there but particles leaves the water and enter the air... Can anyone help me with this problem?? Surface tension water/air is switched on.

Best regards,

Marek.

take into account the drag law at DPM: stokes cunningham active the implicit body force at the VOF model
