CoolProp: Thermal Conductivity Data Missing for R-1233zd(E)

Description

I am unable to calculate thermal conductivity of R-1233zd(E) using CoolProp.

Steps to Reproduce

I create an instance of the AbstractState class (in C#) using the command: fluidName = "R1233zd(E)"; // Use IIR Reference state CoolProp.set_reference_stateS(fluidName, "IIR"); abstractState = AbstractState.factory(equationOfStateString, fluidName);
I update the state by calling: abstractState.update(input_pairs.QT_INPUTS, qualityMolar, temperature);
The thermodynamic properties are properly returned by the abstractState.T(), .p(), .rhomolar(), .Q(), .umolar(), .hmolar(), .smolar(), .cvmolar(), .cpmolar(), and .speed_sound() methods.
I attempt to retrieve the thermal conductivity by calling the AbstractState’s conductivity() method, but I receive the error: “Thermal conductivity model is not available for this fluid”
Viscosity can be calculated by the .viscosity() method, but the result is significantly different than the value returned from Refprop 10.

Expected behavior: I expect that the transport properties can be successfully calculated for R-1233zd(E), using the ECS method if no dedicated correlations are available.

Actual behavior: [What actually happens] .conductivity() method returns an error stating that “Thermal conductivity model is not available for this fluid”.

.viscosity() method returns calculated results, but they are significantly different than results returned from Refprop 10 for the same conditions.

At 275 K, Q = 0: CoolProp .viscosity() returns 0.000620977 Pas. Refprop 10.0 returns 0.0003637 Pas CoolProp/Refprop10 - 1 = 70.7%

At 275 K, Q = 1: CoolProp .viscosity() returns 1.02013E-05 Pas. Refprop 10.0 returns 9.4907E-06 Pas CoolProp/Refprop10 - 1 = 7.49%

CoolProp Version: 6.2.1 Operating System and Version: Windows 10 Enterprise, 64-bit Access Method: I am accessing the pre-compiled CSharp dll using the C# classes provided in the C# platform-independent download.

Ian here…

The data from this publication was used to develop the model in 2016 Purdue paper:

Hulse, R. J. J.; Basu, R. S.; Singh, R. R.; Thomas, R. H. P. Physical Properties of HCFO-1233zd(E) J. Chem. Eng. Data, 2012, 57, 3581-3586

This dataset has since been rejected with the existence of the datasets that you have identified. The entropy scaling model needs to be reparameterized (the constant needs to be updated). I can’t do this work, but you could.

Ian,

Please let me know if/when the thermal conductivity model can be implemented for R1233zd(E).

Regarding the dynamic viscosity, I reviewed summary saturated liquid dynamic viscosity plots from Meng, and from a second paper (Cui, 2018, DOI: 10.1021/acs.jced.7b00902). I compared the results presented by Cui and Meng to Refprop 10 and CoolProp 6.2.1 in the attached excel workbook.

In summary, I find that Refprop, Meng, and Cui are in good agreement, but CoolProp 6.2.1 dynamic viscosity is significantly different. For saturated liquid from 265-430 K, the residual (CP/RP-1, %) varies from from 40-75%. Comparison of R1233zdE Saturated Liquid Dynamic Viscosity Data Sources.xlsx

Note that the images from Cui and Meng, from which viscosity data was extracted for comparison using an image digitizing tool, are from publicly available preview images for each paper.

Thank you, Justin

For thermal conductivity or R-1233zd(E), Refprop 10 uses Perkins (2017). Perkins, R.A., Huber, M.L., and Assael, M.J., “Measurement and Correlation of the Thermal Conductivity of trans-1-Chloro-3,3,3-Trifluoropropene (R1233zd(E)),” J. Chem. Eng. Data, 62(9):2659-2665, 2017. doi: 10.1021/acs.jced.7b00106

Regarding the viscosity, I would like to learn more about the background of the entropy-based viscosity model selection v. ECS.

Note that there is a liquid viscosity publication from Meng, Wen, and Wu (2018). I am unsure if it is useful for development of a general viscosity correlation or if it can be used to tune the ECS method. Meng, X., Wen, C., and Wu, J., "Measurement and Correlation of the Liquid Viscosity of trans-1-Chloro-3,3,3,-trifluoropropene (R1233zd(E)) J. Checm. Thermodynamics. 123, 2018. DOI: 10.1016/j.jct.2018.04.001

Thanks, Justin
