Autodesk CFD Suitability for fume cupboard

Anonymous — Thu, 13 Jul 2017 11:37:31 GMT

Hello,

I work for a company who specialise and manufacture Fume cupboards. We manufacture both ducted and re-circulation units. The basic principles of a fume cupboard is to keep the bad air inside the fume cupboard away from the user and eventually extract the air through ducting and out of the building, or through filters built into the unit and recirculated back into the room as 'clean' air. Containment is the key which is the ability to prevent the contaminated air leaking back into the room through the open sash which is achieved by creating a negative pressure that draws the air up the duct exhaust or into the filters.

Basically we would love the ability to simulate the air flow paths on our models before physical prototyping and type testing. Being able to physically see this on a computer would be a massive help.

Would autodesk cfd be the correct software? Has anyone else used CFD to simulate similar characteristics? We model our fume cupboards in Autodesk inventor, so i assume that importing and assembly into cfd wouldnt be an issue?

Looking forward to your comments.

Many Thanks,

Callum

I used to use our software for consultancy also and have certainly run fume cupboards 🙂

Yes, I would say that we could do this with relative ease. You could even set particle traces up from a region of known contaminant to see where they travel to.

Does that help to answer your question?

Thanks,

Jon

Hi John,

Hi Collum,

Autodesk CFD is easy to use, but still needs a bit of explanation.

That's why we do not throw out trial versions easily.

But feel free to send me an email (dirk.ditschke@autodesk.com) and we figure something out for you.

Hi @Anonymous,

Just a heads up there's two webinars you might find interesting. This analysis would probably be done via scalar mixing. The first webinar shows a smokestack exhausting into an atmosphere. There's an example in the second webinar of a room with with a gas stove exhausting methane (as if pilot/flame is out).

Scalar Mixing Analyses (Part 2)

Thanks,
