    • Abstract


      Boltzmann-transport equation is analytically solved for two-component magnetoplasma using Chapman-Enskog analysis to include collisional diffusion transport having anisotropies in both streaming velocity and temperature components. The modified collisional integrals are analytically solved with flux integrals and perturbed kinetic equation to arrive at drift diffusion velocity and resulting transport coefficients which are markedly affected by both streaming and temperature anisotropy. The early isotropic results are recovered in the limit $V_{0} = 0$ and $T_{\|} = T_{\bot}$ which reduce to eqs (11.30) and (11.31) of [1] and eqs (2.7) and (2.13) of [2]. The electrical resistivity (n_{\bot}) diminishes sharply in fusion temperature limit $kT_{\bot} = 1$ keV. The shape of the curves for both electrical resistivity and thermal conductivity is rectangular hyperbolic. However, for low thermal ratio $(T_{\|}/T_{\bot} < 1)$, the curves are raised up and for high thermal ratio $(T_{\|}/T_{\bot} > 1)$, they are lowered down the isotropic case $(T_{\|}/T_{\bot} > 1)$, showing comparatively diminished magnitudes of the quantities.
