IONIZED PARTICLES AS CONTAMINANT IN A NEUTRAL TURBULENT FLUID.

Abstract

The role of ambipolar diffusion in a turbulent plasma is studied. The turbulence is considered as given, and its spectrum extends up to the viscous cutoff. The charge density is treated as a passive contaminant with a special coefficient of ambipolar diffusion. The cases of large and small ambipolar diffusion are discussed, but a rough estimate shows that the ambipolar diffusion is comparable with the kinematic viscosity, indicating that the plasma charge density cutoff is the same as that of the turbulent spectrum.
