R1234ze(E)

 

R1234ze(E) provides thermodynamic property data for HFO-1234ze(E) (trans 1,3,3,3-tetrafluoropropene, CAS# 29118-24-9. MW 114.04 g/gmole).  The thermodynamic property data are obtained from the equation of state published in:

 

 

I Made Astina,, Galih Budiarso, Richard Harrison

"New Helmholtz Equation of State for HFO-1234ze(E) with Comprehensive  Assessment"

 

The reference state h=200 kJ/kg and s=1.0 kJ/kg-K at 273.15 K for saturated liquid.

 

The properties are valid for temperatures between 170 K and 600 K for pressures up to 100 MPa.

 

Viscosity

Viscosity is determined using the information from:

Huber, M.L., and Assael, M.J.,

"Correlations for the viscosity of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E))"

Int. J. of Refrigeration, Vol 21, pp. 39-45, (2016)

 

Thermal Conductivity

Thermal Conductivity is obtained from the correlation provided by:

Perkins, R.A. and Huber, M.L,

"Measurement and Correlation of the Thermal Conductivity of 2,3,3,3-Tetrafluorprop-1-end (R1234yf) and trans-1,3,3,3-Tetrafluoropropene (R1234ze(E))
