PSV sizing , two phase flow

[dbert]

for sizing PSV with critical and two phase flow (vapor + liquid) I have utilized extensively Excel with Prode Properties as process simulation library

Prode Properties works adding macros in Excel which allow to solve problems in process simulation,
for PSV sizing there is a macro which solves (with rigorous thermodynamics based on selected EOS) a isentropic nozzle model, this macro allows to select from several methods

HEM (Homogeneous Equilibrium Model)
HNE (Homogeneous Non Equilibrium)
HNE-DS (Homogeneous Non Equilibrium, the Diener/Schmidt procedure)
NHNE (Non Homogeneous Non Equilibrium)

I have been requested to validate the results,
while for HEM (Homogeneous Equilibrium Model) and HNE-DS there are several examples in literature
for NHNE (Non Homogeneous Non Equilibrium) I have found little.

Do you know where I can find numerical examples solved with NHNE method ?

[carlo.stenali]

I have had the same problems when evaluating NHNE (Non Homogeneous Non Equilibrium),
at last I decided to fit the parameters of NHNE model to some experimental data and compare results of HEM, HNE and NHNE

[matrenel]

I have seldom utilized the NHNE model,
the operating manual suggests a range of values for parameters ,
in my applications I have found HEM and HNE models adequate for all cases.
