Hello,

I've to check and existing Vacuum Unit transfer line and I wanted to know if there is any paper or spreadsheet/simulation example to learn on how to do this check. I wanto to know if we have chokec flow at any point in the transfer line. Could anybody help? Thanks!!

Daniel001,

 

To start with , you may read the documents attached .

Hope this helps you .

Daniel,

I've specific knowledge of these systems but I don't know how to help you.

For istance, I never needed to analyse the possibility of choked flow...

Unfortunately Breizh docs are not very helpful for your case, ie 2-phase flow at very low pressure with varying L/V ratio.

Could you kindly tell me what is the main diameter of your VTL?

Good luck!
