Electromagnetic turbulent pressure in a plasma of inhomogeneous turbulence
Abstract
A general expression of electromagnetic turbulent pressure in a plasma of inhomogeneous turbulence is derived from Vlasov's equation using the properties of the spectrum of correlation of two fluctuating parameters. It is found that this pressure consists of two parts. One is the electromagnetic ponderomotive force produced by interaction between the nonresonant particles and the turbulent waves. The other is the direct transfer of momentum from the turbulent waves to the plasma through the interaction between the resonant particles and the waves. Corresponding representations of turbulent pressure for some turbulent oscillation modes (Alfvén waves, magnetohydrodynamic waves, whistlers, ionacoustic oscillations, and Langmuir waves) are given for a plasma of Maxwellian distribution.
