摘要
Calculation of the carbon dioxide state equation isotherms in the temperature range from T = 400 K to T = 1700 K is presented. Implemented calculation method is a refinement of the previously proposed approach based on the fractal state equation and specially developed software Fract EOS. The calculation results are in good agreement with the experimental data. It is shown, that the fitting parameter alpha of the fractal state equation for carbon dioxide does not depend on temperature. The density dependence can be accurately approximated using the polynomial. This fact simplifies the calculation of isotherms in a wide temperature range, and allowed to make the calculation for temperatures, that are not presented in the tabular reference data. The obtained results show that the proposed equation of state is suitable for studying not only simple substances like noble gases, but also for more complex substances, such as carbon dioxide.
