My company is trying to model humidification using an AKIMist.
Here is a link to the product: https://www.ikeuchi.us/eng/products/unit/1003
We are ignoring water injection/particles and only focusing on the air pattern. We are assuming that the particles of water will settle where ever the air goes.
Im concerned that modeling the nozzles would be difficult because they are so small compared to the room that they are in. There are three nozzles shooting towards each other with holes around a millimetre in diameter. This impact created the fine mist that humidifies. This would require a very small mesh compared to the room it would be in (52 ft long, 20 ft wide, 18 ft high).
I was hoping you could connect me with someone who may have experience that could help us find a good solution to being able to model these humidifies to study the best placements of them in a room for uniform humidification.
We currently have access to both Discovery AIM as well as Discovery Live.
We would love to hear back and setup a screenshare meeting if able.

This is an interesting problem!
Let me discuss it with the concerned experts and get back to you.

Since you will be modeling it as single phase single species problem, the only limitation may come from mesh count. Roughly, around 2.5-3.5 GB per million converted polyhedra cells can be consumed while solving. If you have 64 GB RAM machine and can manage geometry capturing with 15 millions converted polyhedra mesh, then there is some chance of running the simulation. Otherwise, try with splitting the fluid domain, putting hex mesh in most of the part and small tet mesh near nozzle.
Please let me know if you have any further questions.

Naresh Patre So essentially you are saying that the small size of the nozzles shouldnt be a problem for the program. I have 80 GB of RAM so ill just see how many elements I can get to. I will report back.

So I ended up modeling the humidifiers using the particle emitting option in Discovery AIM and information about the average particle size from the humidifier manufacturer. I was wondering if there are any examples you could point me to using the particle emitter feature in hopes of improving my application of it.

I don't have any example readily available. I am checking with the team and will let you know if there is any.
