Abstract:

According to the analysis of kinetic equations of particles in plasmas given in a previous report On Transport Processes in a Plasma Kinetic Equation for a Plasma, AFOSR 1744, USCEC Rept 83-209, October 1961., rarefaction of a plasma is defined. The criterion of rarefaction is divided into two parts one is the condition of the discrete binary interactions of particles which permits us to define a free path the other is the comparison between the mean free path and A REPRESENTATIVE DIMENSION OF THE FIELD the Knudsen number. The first condition is determined by the number density of particles and the temperature the average energy of random motions of particles. In the regime of rarefaction, the basic kinetic equations are of the Boltzmann type. Author
