Effect of streaming and temperature anisotropy in Wiedemann-Franz law for collisional magnetoplasma

Abstract

The presence of beam in a two component fully ionized electron-ion magneto plasma entails streaming or mass motion of plasma species causing energy dissipation. The collisional diffusion transport coefficients are significantly modified in presence of the streaming velocity. Further these coefficients are also found to be modified owing to anisotropy in plasma species temperature. The modified transport coefficients result in significant modifications of Wiedemann-Franz ratio in terms of streaming velocity and temperatures along and perpendicular to the direction of field.
