Hello ,
Currently I am working with Centrifugal compressor seal gas system, .It is an existing system and I need to find the leakage rate through the labyrinth. Can somebody please guide me where can I find " Egli, A. 1935. The leakage of steam through labyrinth seals. Transactions of ASME 57:115–122" this paper? If somebody has it already I would really appreciate that.
Regards
Yasir

I do not know about this article. You need to be more specific, which labyrinth? dry gas seals? process labyrinth, intermediate buffer, tertiary seal?

I suggest anyway a book "Rules of Thumb for Mechanical Engineers" - J. Edward Pope.
Go to the section "seals" there you can find some formula how to calculate the leakage vs. geometry/design (no. of teeth, step, width, etc.).
I suppose since it is an exisiting system, you have the drawings at hand to input some geometric data. And you need process data as well.

Hi,
Thanks for taking out time to reply. Actually i am working with Dry Gas seals. The arrangement of seals are of tandem type.Over the years Seals are failing because of leakage. So i need to find out the leakage rate through process labyrinth. I have checked the book you suggested but it does not have formulas for process labyrinth leakage rate. Can you please guide me further in right direction. i will really appreciate your help in this regard.

Regards

Yasir

sorry, it is this one:

Mechanical Design, 2nd Edition, P. Childs - Pub. El Sevier 2004

Attached a screenshot of a tool I made of my own based on the book's formula.
