Abstract
<p>A plasma fluid code B2 has been benchmarked with a one-dimensional plasma fluid model incorporating the anisotropic ion pressures (AIP model) on simple mirror configurations. In a low collisionality case, profiles of plasma parameters of the B2 code deviate from those of the AIP model. The validity of the viscous-flux approximation is investigated by direct comparisons with the anisotropic part of the ion pressure indicating the invalidity of the viscous-flux approximation is considered to be responsible to deviations of profiles. In addition, supersonic plasma flows downstream from the mirror throat are observed.</p>
