Scientific paper

A rigorous comparison is made of a semikinetic model and the bi-Maxwellian-based 16-moment transport equations for polar wind conditions. The comparisons show remarkably close agreement in the corresponding predictions for the altitudinal variation of the various plasma parameters. These results indicate that the bi-Maxwellian-based transport equations are a powerful tool for modeling a wide range of thermal plasma flows throughout the solar-terrestrial environment. In the collisionless limit, the results indicate that the 16-moment transport equations are equivalent to the kinetic models commonly used in solar and polar wind studies.
