Rifling Design - Machining Limitations 3

[pmbov]

Hi there,
I am looking at adding a rifling design through a fluid cavity to "swirl" the flow as it passes through. Does anyone know what is the size limitations to manufacture this feature? Diameter, Length, Clearances, etc....

Thank you in advance for your help!

This should improve droplet breakup. The pressures are around 4-6 bar (approx. 58-87 psi) for this application.

So. A fuel injector? Did I guess right? Can you just buy one?
