Abstract

New results obtained for thermal conduction in 2D Yukawa systems. The results of numerical study of heat transfer processes for quasi equilibrium systems with parameters close to conditions in laboratory experiments with dusty plasma are presented. The Green-Kubo relations are used to calculate thermal conductivity and diffusivity coefficients. For the first time the influence of dissipation (friction) on the heat transfer in non-ideal systems is studied. New approximation is suggested for thermal diffusivity. The comparison with the existing experimental and numerical results is shown.
