Bi maxwellian distribution
Webplasma is the Maxwellian (Gaussian) distribution. The average velocity spread (variance) is, = (2kBT/m)1/2, and the mean drift velocity, v 0. Anisotropic model velocity distributions The most common anisotropic VDF in a uniform thermal plasma is the bi-Maxwellian distribution. Left figure shows a sketch of it, with T⊥> T⎢⎢. Webdistribution function which is supposed to be a local bi-Maxwellian. In section 3., we present a theoretical analysis of the Weibel modes. The section 4. is devoted to the …

We have looked into some … WebJul 14, 2024 · The bi-Maxwellian distribution gives accurate results for the ionization and excitation rates but fails in the electron mobility at low energies. Similarly, a Druyvesteyn EEDF does not match with the values obtained with the Boltzmann equation. On the other hand, the Maxwellian distribution considerably overestimates the values.
