Vortex Breaker Article
(OP)
In thread124-222509: vortex breakers a number of people refer to the link below. This link no longer works and I am very interested in reading this article as I may be having a problem with a flash vessel that is cavitating due to vortex formation (it doesn't have a lid/ cover - DN 850 nozzle with just 4 cross plates).

There is much industry experience with pump cavitation.... but not vessels
Can you show us vessel drawings, describe process conditions and further explain the problem ?
The only flash vessel I have had experience with are those associated with boiler blowdown.... these vessels are designed to encourage internal vortex flow to disengage flash steam from condensate.
Pumps drawing from boiler blowdown vessels frequently have transient NPSHa problems and cavitation problems are frequent.
Is this your problem ?

A four cross plate will get you quite a long way, but 850 nozzle is quite big. You must be getting a large flowrate / velocity?

A number of previous threads have referred to the link I posted in the original post suggesting it specifically discusses this topic. I just want to read that article if anyone saved a copy :)
The flowrate is large hence the DN 850 nozzle and the submergence is adequate based on ANSI however CFD results indicate vapour carry under and that the plate would be beneficial to prevent this. Hence I am looking for articles that discuss this topic.
