“…In the case of n-perfluorohexane a large amount of pure component experimental data is available [40][41][42][43]. Although more limited, some experimental data are also available in the literature for n-perfluoroheptane [41,[44][45][46].…”

We report measurements of logarithmic temperature profiles Θ(z, r) = A(r) × ln(z/L) + B(r) in the bulk of turbulent Rayleigh-Bénard convection (here Θ is a scaled and timeaveraged local temperature in the fluid, z is the vertical and r the radial position, and L is the sample height). Two samples had aspect ratios Γ ≡ D/L = 1.00 and 0.50 (where D = 190 mm is the diameter). The fluid was a fluorocarbon with a Prandtl number of Pr = 12.3. The measurements covered the Rayleigh-number range 2 × 10 10 Ra 2 × 10 11 for Γ = 1.00 and 3 × 10 11 Ra 2 × 10 12 for Γ = 0.50. In contradistinction to what had been found for Γ = 0.50 and Pr = 0.78 by Ahlers et al. (Phys. measurements revealed no Ra dependence of the amplitude A(r) of the logarithmic term. Within the experimental resolution, the amplitude was also found to be independent of Γ . It varied with r in a manner consistent with the function A(ξ ) = A 1 / 2ξ − ξ 2 , where ξ ≡ (R − r)/R with R = D/2 and A 1 0.0016. The results for A(r) are smaller than those obtained from experiments and direct numerical simulations (Ahlers et al., Phys. Rev. Lett., vol. 109, 2012, art. 114501) at similar values of Ra for Pr = 0.7 and Γ = 1 2 by a factor that depended slightly upon Ra but was close to 2.

“…Simulations were carried out at high temperatures, and the saturation pressure at 273 K was obtained by extrapolation using the Clausius-Clapeyron equation. It was estimated that at 273 K, the saturation pressure for PFH is 0.144 bar, which is slightly higher than the values reported by National Institute of Standards and Technology (NIST) (Crowder et al, 1967;Lemmon et al).…”

We combine two approaches to describe an activated carbon which contains micro-and mesopores. We propose a simple approach of packing individual three-dimensional rigid structures to represent microporous region of commercially available BAM-P109 activated carbon. Mesopores are represented by planar walls interacting via the standard Steele 10-4-3 potential assuming experimental pore-size distribution. The models are used to predict n-perfluorohexane adsorption at 273 K temperature. We used uncharged united atom model for n-perfluorohexane molecule. The non-bonded interactions were described by the Gordon potential model, with parameters adjusted to reproduce the Mie force field potential, which was designed to accurately represent vapour pressure of alkanes and perfluoroalkanes. Adsorption isotherm was calculated using Grand Canonical Monte Carlo method implemented in MCCCS Towhee. We show that predicted n-perfluorohexane loading at relative pressures of interest are significantly lower than the experimental ones. The underprediction is attributed to the low aromatic carbon interaction strength and sensitive calculations of chemical potential. Adjusted interaction parameter of aromatic carbon and chemical potential led to n-perfluorohexane adsorption that agreed well with the reported experimental values.
