Warning message on non radial nozzles for WRC Calculations on PV Elite

[scorpio2310]

Dear all
While designing the nozzles on Dished heads, I receive below warning message on PV Elite calculation. Please advise we can ignore the warning or Finite element Analysis (FEA) is mandatory for such type of all Warnings

-----------------------------------------------------------
Warning:
The equations for nozzle local stress analysis pertain to radial nozzles only
and this nozzle is not specified as radial. Please check the specific
analysis code for all assumptions and limitations.
-----------------------------------------------------------

 

[TGS4]

For starters, I would recommend that you "check the specific analysis code for all assumptions and limitations." Have you done that?

Talking off the top of my head here, but I believe WRC 107 will analyze a nozzle on a spherical shell. Thus WRC analysis should be valid for a nozzle on the head centerline. You'd most likely check the "radial nozzle" checkbox and use the head spherical radius.

Check the PVE documentation, and yes, follow TGS4's advice.

Mike


The problem with sloppy work is that the supply FAR EXCEEDS the demand
