Lattice Boltzmann Simulations of Electrostatic Plasma Turbulence

摘要

A Lattice Boltzmann algorithm to study the 3-D electrostatic-turbulence dynamics in thermonuclear plasmas is presented. The ion continuity, momentum and pressure equations are reproduced with the electrons being described by the adiabatic response. Applications to the study of 2-D turbulence show that the heat flux is reduced at a level much smaller than the quasilinear estimate.
