There is a lot of an emperical component to vacuum jet design and manufacturing. Speaking for my experience with at least one of them, they calculate a design and then make one and test it. If it works as designed, then they produce curves and that becomes the performance standard for that particular design. Change something and they have to do the process all over again.Over the years they have done enough tests that they can exptrapolate from those that they have tested so they rarely have to verify by testing these days, but they have the labs and test stands to do so if needs be.rmw RE: Steam ejector design (Chemical) 22 Dec 08 17:39. This list of references was sent to me by Matija Gregorka. I have not checked them myself.1.

Steam ejector design formz (Chemical) (OP) 6 Dec 08 18:42. Good afternoon, I am now trying to calculate a steam ejector for vacuum production. Does anyone have some suggestions about where (how) to start or a spreadsheet already done for an application like this? Thank you very much in advance.
