摘要
The laws of Ohm, Fourier, and Navier-Stokes for an ionized gas are obtained from a simple method that combines the features of the methods of Chapman-Enskog and Grad. The transport coefficients are easily determined through inversions of second-order and fourth-order tensors. This work is based on the Boltzmann equation for ionized gases, where (i) the preponderant number of collisions are those that lead to small deflections corresponding to distant encounters; and (ii) a cutoff at the Debye length has to be considered. © 1995 American Institute of Physics.
