Abstract
The caloric and thermal equations of state, composition, and conductivity have been calculated for a supercritical aluminum plasma fluid. A previously proposed chemical plasma model called the “3+”-component one was used for the calculations. The model includes atoms, electrons, ions, and an electron jellium. The thermodynamic functions have been calculated for the first time within the “3+” model for a plasma fluid. The magnification and compensation of intercharge and interatomic interactions when calculating the equation of state and composition are analyzed. The introduction of the jellium leads to an increase in conductivity under compression, while the compensation of interactions when calculating the composition leads to a virtually ideal-gas behavior of the equation of state. Comparison with the data from physical and numerical experiments has confirmed our conclusions and demonstrated that the hypothesis about jellium, a new gas–plasma component, is constructive.
