“…6. In the region of relatively low temperatures, significant errors in the calculated values of entropy with corrections may appear due to the use of a simple approximation for the Fermi -Dirac functions, while there are more complex analogues [13,14]. It is shown in [15,16] that the calculation of internal energy and entropy according to the Thomas -Fermi model is less accurate than that of pressure, so in the temperature range (T < 100 eV), quantum exchange corrections can give nonphysical results.…”

Numerical modelling of the thermodynamic properties of plasma mixture is performed using the Thomas – Fermi model with two different approaches. For this purpose, a numerical algorithm, as well as program realization, is developed to solve the Thomas – Fermi equations with quantum-exchange corrections. For the first time a comparison between different methods for taking account of the heterogeneous composition of plasma is made and an algorithm for estimating the corrections for mixtures is developed.
