Hi!

I would like to use the Fluent wet steam model to simulate the steam flow in a flow nozzle for mass flow measurement (differential pressure method).

The aim is:

1.: to determine the minimum superheat of the steam, that condensation due to the pressure drop in the nozzle is avoided.

2.: To estimate the error in mass flow measurement, when superheat is to low and condensation in the nozzle occurs.

Has someone done something similar? Are there any experimental or numerical literature data to compare results?

The flow is NOT sonic and NOT transonic!!!

Thank You!
Ralf
