Modelling particle accumulation

siw · May 24, 2011, 11:47

Hi,

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?

Thanks

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.
