An electron conductivity model for dense plasmas

TLDR

The model is useful for simulating plasma experiments with strong magnetic fields. The study introduces an electron conductivity model for dense plasmas that delivers a comprehensive set of transport coefficients. The model employs different formulas for electron relaxation time across plasma, liquid, and solid phases to compute electrical, thermal, thermoelectric, Hall, Nernst, Ettinghausen, and Leduc–Righi coefficients. The coefficients are valid over a wide temperature and density range, are computationally simple, and match recent calculations and experiments, proving accurate for practical use.

Abstract

An electron conductivity model for dense plasmas is described which gives a consistent and complete set of transport coefficients including not only electrical conductivity and thermal conductivity, but also thermoelectric power, and Hall, Nernst, Ettinghausen, and Leduc–Righi coefficients. The model is useful for simulating plasma experiments with strong magnetic fields. The coefficients apply over a wide range of plasma temperature and density and are expressed in a computationally simple form. Different formulas are used for the electron relaxation time in plasma, liquid, and solid phases. Comparisons with recent calculations and available experimental measurement show the model gives results which are sufficiently accurate for many practical applications.
