Modeling Particule Generation and Concentration in Cleanrooms

[sharbel.elhaber]

Dear Community Members,

I am a new Autodesk CFD user. Is it possible to model accurately particle generation and concentration in a cleanroom? I saw in the software manual that scalar mixing can be used. Any thoughts on how to model this problem efficiently and reliably?

Thank you in advance.

It depends on the source. You could probably use a scalar analysis here I would think though. But how you add the particles (scalar 1, if scalar 0 = clear air) to the model will be key.

Could be possible though.

Thank you for your response.

Should a scalar analysis be used, would it be possible to track the number of articles?

Thanks again.

Hi @sharbel.elhaber,

You might want to check out this scalar mixing webinar. There's a great example of something similar to particulate concentration. An analysis is done of a kitchen area with methane coming out of the burners and eventually exhausting through a window. The summary file will show the user percent volume of the entire fluid domain that has certain concentrations  of a scalar. 

I think it would be super helpful in answering your questions.

Thanks,
