“…This was selected because it results in the gas-phase thermal conductivity of a related fluid, perfluoropropane, to be within ~10 % of experimental data. Only one valid liquid-phase thermal conductivity data point was found (Irving & Jamieson, 1975), and this, along with family behavior, was used to obtain the coefficients in Table 3. Parameters for the critical enhancement are presented in Table 4.…”

We describe models for the viscosity, thermal conductivity, and surface tension for selected fluids implemented in version 10.0 of the NIST computer program, NIST Standard Reference Database 23, also known as NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP). These fluids do not presently have published reference fluid quality models in the open literature, so we provide preliminary models based on available data as an interim measure to allow calculations of these properties. Comparisons with available experimental data are given.

“…For thermal conductivity, we used the same value of ao as was used for perfluoropentane. For the liquid, we fit the data of Irving and Jamieson (Irving & Jamieson, 1975) to obtain the coefficients in Table 3, and a deviation plot is shown in Figure 162. Parameters for the critical enhancement are presented in Table 4.…”

“…The f‐theory model for thermal conductivity has been optimized by regressing the friction coefficients on the only three liquid data at ambient pressure available for C 6 F 6 from Irving et al [ 45 ] Additional data obtained by the interpolation of the Irving experimental data were needed to find the nine friction coefficients. For a better fitting procedure, more experimental points would be necessary.…”

Transcritical cycles working with CO2‐based mixtures gain considerable attention due to thermodynamic efficiency gain compared to pure sCO2 in hot environments. Previous literature works prove that the adoption of CO2 mixtures provides a reduction of the levelized cost of electricity in concentrated solar power applications and medium–high temperature heat recovery. However, for techno‐economic analysis and heat exchanger design, proper evaluation of transport properties of the CO2‐based mixtures in power cycle conditions is necessary. Herein, it deals with the analysis of the proper transport properties models for CO2 mixtures to assess their actual thermal behavior. A literature review on transport properties models, and their validation with available experimental data, proves that the friction theory is suitable for CO2 blended with dopants having high molecular complexity. The impact of the different model selection on the recuperator sizing, considering optimized power cycle conditions, is assessed on the CO2 mixtures with hexafluorobenzene and decane: The TRAPP and Chung–Lee–Starling models are imported from Aspen Plus, while the friction theory model is implemented and calibrated in an in‐house MATLAB code. The optimal design of the recuperator for the CO2 + C6F6 mixture in a 100 MWel power block coupled with a solar power plant located in Sevilla is carried out.

Fluorinated compounds often have distinctive properties. In this chapter, the physical properties of fluorinated compounds are discussed. First, the characteristics of the fluorine atom itself are explained, followed by the characteristics of the CF bond and its associated stereoelectronic effects. This allows understanding of the electronic and steric effects of fluorine and fluorinated groups, which is discussed in the following sections, as well as the influence of fluorination on macroscopic properties, discussed in the final section.
