Discrete phase modeling on porous media
 

Hi everybody, I need to model particles lifted by air in a channel. The channel ends with a porous surface, which is the basis of a porous volume. This surface is moving and it let particles to escape from channel, while air has to pass through porous media and then flow out. Unfortunatly, even with very high inertial and viscous coefficient for porous media, particles passes through porous media, while they should stop on its surface. Has anybody experiencewith this kind of problem?
Thanks in advance
