Does anyone know what to call this sort of fan optimization or have any reading material on how it works or how to design them? (sh.itjust.works)

I'm trying to find out what purpose this type of design serves and how they are designed but have hit a wall with knowing what to even look for.

This piece of the voron stealthburner is the only example I can think of off the top of my head but I have seen them before in some sort of fan duct or funnel thing.

They discuss it in some detail in one of the Voron Live talks - I think this one, which was the announcement video for Stealthburner. Lots of CFD combined with manufacturability testing and aesthetics mixed in too.

Edited to add: oh, that’s the hot end fan. I don’t remember if they discussed that or just the part cooling fan, but the video is an interesting watch either way.

Oh yeah. They put a lot of thought into it. I’d say it’s probably one of the more over engineered bits… but they’re all kinds over engineered… heh.
