The Viscosity and Thermal Conductivity Coefficients of Gaseous and Liquid Fluorine

Abstract

Tahles of values for the viscosity and thermal conductivity of fluorine are presented in the ~ange 70.300 K fo~ pressures uP. to 200 atmospheres. Experimental results were reviewed hut were Judged to he unre~lahle. Accordmgly, dilut~ g~s values were determined from kinetic theory using the m-6-8 po~e~tlal, ~nd dense ga~ and hquld values were obtained from the modified Enskog theory. The critIcal pomt anomaly m the thermal conductivity coefficient is also discussed.

Models for viscosity, thermal conductivity, and surface tension of selected pure fluids as implemented in REFPROP v10.0

“…We estimate the uncertainty in the viscosity in the gas phase and along the liquid saturation boundary to be 20 % (based on Hanley and Prydz (Hanley & Prydz, 1972) estimates of their data). Similarly we used Hanley and Prydz (Hanley & Prydz, 1972) dilute-gas and saturated liquid values to obtain the coefficients in Table 3, with deviations shown in Fig. 197.…”

“…LennardJones parameters were taken from Reid et al (Reid, 1987). There are few experimental data for this fluid, so we relied heavily on predictions provided by Hanley and Prydz (Hanley & Prydz, 1972), who reviewed existing data and found most to be unreliable. We used recommended values for the saturated liquid viscosity and dilute gas viscosity from Hanley and Prydz (Hanley & Prydz, 1972) and the data of Elverum and Doescher (Elverum & Doescher, 1952) to obtain the coefficients in Table 2, and Figure 196 shows a deviation plot.…”

Effective Intermolecular Interaction Potentials of Gaseous Fluorine, Chlorine, Bromine, and Iodine

“…The potential parameters were based on experimental viscosity data [2][3][4][5][6]. In 1972, Hanley and Prydz [7] obtained (m − 6 − 8) potential parameters by fitting the B data, published by Prydz and Straty [8], and presented tables with calculated values for the thermal conductivity λ and viscosity η of gaseous and liquid F 2 in the temperature range between 70 K and 300 K for pressures up to 200 bar.…”
