Dear all,
I am designing a shell and tube heat exchanger with the following process characteristics:
-Tube Side: Gas Refrigerant
-Shell Side: Fresh Water
I get a constraint from general installation of my project to put "axial inlet nozzle" on tube side and I have a warning on HTRI software which is a copy/paste from TEMA:
"Consideration shall be give to the need for special devices to prevent erosion of the tube ends under the Following conditions:
- Use of axial inlet nozzle
- Liquid pv2 in excess of 6000 (8928)…."
Regarding the pv2 criteria, I am very far from this limit however I do get an axial inlet nozzle.
My question is quite simple, I don't get the requirement, which special device am I supposed to provide due to the fact I use axial inlet nozzle, if any ? Or is it just generic warning message?
Thanks in advance, I did not find any similar topic on internet.
