Studies on Fluorine at Low Temperatures. V. Viscosity of Fluorine Gas at Low Temperatures

The Viscosity and Thermal Conductivity Coefficients of Gaseous and Liquid Fluorine

“…The experimental situation was first investigated, and it was apparent at once that the data available were scarce and scattered. A literature search carried out by the CryogeniC Data Center, National Bureau of Standards, Boulder, yielded the following experimental references applicable for temperatures less than 300 K: liquid viscosity [2J~4 liquid thermal conductivity [19], dilute gas viscosity [4,10], and dilute gas thermal conductivity [3]. We plot data from these references in figures 1 and 2.…”

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

“…In the case of F 2 , Fig. 1, a systematic deviation of more than ±1a exp of the viscosity data of Kanda [2] is observed. This large inconsistency of these data was already mentioned by Hanley and Prydz [7].…”

“…[15] Fig. 2 Deviations P exp − P calc between experimental and calculated properties P = B, β, or η for Cl 2 normalized to their individual experimental uncertainties a exp . Calculations are carried out with an (n − 6) LJTDP by using the potential parameters given in Table 2 within their stated limits of accuracy.…”

“…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.…”
