Particle deposition in DPM simulations
 

Hello everyone,

I have been scouring the web for weeks now and haven't been able to get a solution for this. I am running a transient simulation wherein I inject small water droplets (10 micron) into the flow from the inlet. The geometry is complex with a pipe splitting to many branches. I have set the wall boundary condition to trap the particles. All well and good.
Now my dilemma is how exactly do I postprocess this information. I would like to display the accumulation of particles on the walls as a function of time.. Nothing that I have tried so far gives anything close to this. I have even tried the accretion option to display contours, but this doesn't really show what I am after. Any help and guidance is appreciated! :)

Thanks!

Hi there,

Just wondering if you had any luck with this? I am trying to do something similar at the moment? :)

I hope you had run one iteration after turning on the acceration option, if yes then, i think u will get what you are trying to display

hi,

i am not 100% sure but i think you should adjust the monitor section before the run for this purpose.

you need the create surface monitor. area-weighted-average, DPM-DPM concentration etc..

hope this helps!

Thanks for the replies.. I found the closest answer to my question in this post

Hope it helps others as well. :)

Makes more sense now. Thanks for your help !
