• A turbulence model for the generalized Ohm's law in partially ionized plasmas with the spatial gradient of electrical conductivity is proposed. The present model suggests that when there is a spatial gradient of electrical conductivity, 〓σ, on a plane perpendicular to the magnetic field, fluctuating motions of partially ionized plasmas are anisotropically suppressed, even on the perpendicular plane, due to the anisotropic Lorentz force exerted on the plasma. As a result, we insist that the application of a magnetic field perpendicular to 〓σ induces a steady mass flow directed to 〓σ, which alters the mean profiles of the temperature and velocity fields. It has also been shown that with increasing temperature fluctuations, the effective conductivity in the present model decreases, although the time-averaged conductivity increases because of the nonlinear dependence of the conductivity on temperature.
