hello!
 
I want to get the Transport Properties (Based on Venus model) of R11  .
I am using the online website to calculate:http://www.ethermo.us/ShowDetail31.htm.
 
Is there any other website or APP for physical calculations?
 
thanks :)

many of these web sites adopt the Nist Refprop formulations

 

https://www.nist.gov/srd/refprop

 

for refrigerants Refprop includes  MBWR, Bender etc. EOS models (depending from fluid),

 

there are clones (i.e. fortran or c++ conversion) as coolprop etc.

 

for pure fluids (and some predefined mixtures) these are probably the most accurate sources available,

 

Nist has a online page

 

http://webbook.nist....hemistry/fluid/

 

of course there are other apps, I have Prode Properties, see prode.com,  more reliable for phase equilibria, however for R11 the  BWR model (in Prode) is a bit less accurate than Refprop,

other members here have simulators, I can't say how accurate are the different models for R11.
