I would like to simulate particle flow through a screen.
In the screen setting, only the free area ratio of thin perforated plate can be defined.
How do I know if the particle is able to flow through the screen as the hole diameter
and the number of holes cannot be input?
Solution
When defining the Screen simulation object, turn on the "Pass-Through" toggle to obtain a report on the number of particles passing through the screen.
The free area ratio is used to calculate a head loss coefficient at the screen. However, it is not used to determine whether the particles are trapped by the screen based on a comparison between the perforation and particle diameters.
