Determination of the Potential Energy Function of CF4−CF4 via the Inversion of Reduced Viscosity Collision Integrals at Zero Pressure

“…It is obvious that there exists a very good accordance between the experimental values 13,22-24 and our calculated values in the temperature range from 150 to 3500 K at atmospheric pressure. The experimental and our calculated values of viscosity obey the equation This equation works very well in the higher temperature range than the previous equations for calculation of the viscosity of CF 4 : 11,25 Figure 4 shows our calculated self-diffusion coefficient values of CF 4 at atmospheric pressure at different temperatures and experimental data. We have also derived an equation for the calculation of the selfdiffusion coefficients of CF 4 at atmospheric pressure in the temperature range from 200 to 3300 K:…”

“…The experimental determination of these toxic and aggressive gases in a wide range of temperatures is complicated and expensive. 11 Thus, the second objective of the present work is to compute the transport properties of CF 4 at different temperatures and pressures. For this reason, we have computed necessary collision integrals of CF 4 at zero pressure that are needed for calculating the transport coefficients of CF 4 at any pressure.…”

Determination of potential energy functions and calculation transport properties of oxygen and nitric oxide via the inversion of reduced viscosity collision integrals at zero pressure

“…It is obvious that our calculated collision integrals which have been computed using the potentials can reproduce the transport properties in a reasonable agreement with the literature data. We have computed the statistical parameters [35,36], namely, the absolute average deviation (AAD), the average percentual deviation (bias), and the root mean square deviation (RMSD) between our calculated values of transport properties and the literature data and presented in Table 5. In the case of oxygen, the viscosity and thermal conduc- [25], (s) [26] and nitric oxide (,) [20], (h) [33].…”
