Boundary fill in pressure-swirl injector (problem with tangential inlet slots)

[Anonymous]

Hi!

I am a newcomer to Fusion 360, and I am currently trying to model a pressure-swirl injector in it in order to use it on CFD analysis.

The problem is that I need the volume through which the fluid particles will travel, since this is the geometry the CFD software requires for meshing. But to this moment I have not been able to get this geometry, mainly because of the tangential inlet slots (which are shown in the image attached). I have tried using Patch to cover the hole and further using Boundary Fill, but I haven't had success.

I need these slots (holes) to be filled (along with the injector swirl chamber), but I cannot find a way to solve this. If anyone could help, I would really appreciate!

Best regards

PS: I attached both an image of the injector and the injector file.

Is this the kind of thing you're looking for?

Exactly! How did you manage to do this?

Take a look at the model I attached. I'm sure someone else could've come up with a more elegant solution but here's what I did:

1. Deleted your 'capping surfaces'
2. Copied and pasted the body
3. Deleted all the faces of the swirl holes and chamber to give a solid body (ie no internals)
4. Combined (cut) one body from the other to create a new component representing the internal volume

That's it. Glad it was useful.
