Equation of State, Composition, and Conductivity of Supercritical Iron Vapor in the Plasma Fluid Model

详细

The caloric and thermal equations of state, composition, and conductivity of supercritical iron vapor were calculated with the previously proposed chemical model 3+. This model considers atoms, electrons, ions, and jellium, taking into account interatomic and intercharge interactions. The introduction of jellium enables makes it possible to describe ionization via pressure and explain the increase in fluid conductivity under compression. The cohesive atom bonds due to jellium weakens the effect of intercharge interactions on the equation of state. Comparison with the experimental data makes it possible to recommend the proposed plasma model for calculation of the properties of plasma fluid, i.e., an unusual gas-plasma state of matter with the density of a liquid.
