Clogging in pipe and nozzle

Dear All,

I am a novice user. I would like to simulate clogging in pipe and nozzle.
The cause of clogging is solid particle inside the fluid which deposits along the pipe and the nozzle tip.

Do you think which modules I should select ?
(Should it be Microfluidic (two-phase flow), or FSI or any others module )
Are there any models related to my problem ?

Please advice...

Best Regards,
