Is there any way to simulate particles (greater than 50 microns) using filters in ansys fluent? Like using mpm or dpm models?

What do you want to find out? 

[Aravinth Ekamparam]

I want to capture the filtration efficiency of a particular filter for removing colloidal particles in water.

[Aravinth Ekamparam]

Also, I want to capture the particle trajectory and pressure on the filter because of particle tracking.

[Rob]

OK, so you want to see the particles being caught by the filter material? Ie model every last strand and fibre?

[Aravinth Ekamparam]

I do not want to do the simulation to that extent.

I want to see the effect of cross-flow in self-cleansing of the filter. Can this be simulated in the fluent using dpm model?

[Rob]

Sort of, read up on the porous media model (it's a cell zone condition). There are lots of things we can simulate, and in most cases it's more a question of you understanding the physics of the problem to then apply the software.
