Experimental study of heat transfer processes for macroparticles in a dusty plasma

The results of the experimental study of heat transfer processes in liquid dusty structures are reported. The experiments have been carried out for aluminum oxide particles in an rf discharge plasma. The thermal conductivity and thermal diffusivity of the dusty plasma component have been determined by analyzing the steady and unsteady heat transfer processes. The temperature dependence has been obtained for these quantities, which is in qualitative agreement with numerical simulation results for a simple one-atomic fluid.
