Hi
I'm trying to simulate a gas flow containing solid particles through a gas dispersion plate in a conditioning tower. The problem is that the grid is way courser than the 3mm thin baffleplate (220mm, since the entire model is 51000mm). So how can i represent the geometry and still allow particles to flow through it? Will a 2D sub-grid baffle allow for particle flow-through? With a 1000Pa pressure drop. I'm using CPFD Barracuda Virtual Reactor

Regards
Fredrik

Depending on the exact physics in the problem you might be able to solve the gas and powder/particle phases separately with a DEM approach. I know of at least one solver that will let you import an air flow field that provides momentum to the DEM particles.
