Calculation of thermophysical properties of titanium and zinc plasmas

Abstract

Thermophysical properties such as electron transport coefficients, ion composition, pressure, and internal energy are calculated for the plasma of titanium and zinc with densities 10–20 times less than normal density and at temperatures of 10–60 kK. The relaxation-time approximation and the generalized chemical model are used for calculations. The results obtained are compared with the data of experiments and calculation results of other researchers. For titanium, a good agreement with available experimental data and results of calculations by other models, including the first-principles calculations, is obtained, whereas, for zinc, a discrepancy between results of theoretical models and data of measurements for electrical conductivity is observed, which does not yet have an explanation.
