Electronic transport coefficients for dense partially degenerate plasma mixtures

ORAL

Abstract

In this talk, we derive electronic transport coefficients for dense, partially degenerate plasmas based on the extension of a new multiphysics, conservative, entropic Bhatnagar-Gross-Krook model [1,2] to include quantum effects for the electron species. We compare to the commonly used model Lee and More [3], which uses a simpler Krook model and neglects electron-electron collisions. We also discuss the role of the ionization state ⟨Z⟩ in the validity of these expansions.
