INVESTIGATION OF TRANSPORT PROPERTIES OF INERTIAL CONFINEMENT FUSION DENSE PLASMAS

Abstract

In this paper the transport properties of inertial confinement fusion non-isothermal dense deuterium-tritium plasmas were studied. Based on the effective interaction potentials between particles, the Coulomb logarithm for a two-temperature nonisothermal dense plasma was obtained. These potentials take into consideration long-range multi-particle screening effects and short-range quantum-mechanical effects in two-temperature plasmas. Diffusion, viscosity and thermalconductivity coefficients in such plasmas were studied using the Coulomb logarithm. The obtained results are in good agreement with the results of molecular dynamics with the density functional theory used to describe the electron component of the plasma and quantum molecular dynamics simulation at a value , and therefore the effective potential method can be used in this regime. The obtained data show that the transport properties of dense plasma can be adequately expressed in terms of the Coulomb logarithm based on the effective potentials.
