siw will become famous soon enough

I need to model a system which has particles being injected in to it with the airflow. But within the system the particles accumulate and do not exit the fluid domain with the airflow.

I usually use CFX but it cannot model particle accumulation, in CFX whatever particles flow into the fluid domain must also exit it.

Can Fluent model this type of flow?

alighaffari is on a distinguished road
I am not so familiar with CFX but in fluent you can do this. fluent has several types of BC for DPM model.for example i think reflect BC type will be appropriate for your case.for more information see chapter 22 of fluent6.3 users guide.
