Plasma modeling

Plasma modeling refers to a model to describe the state of a plasma. There are three main types of plasma models: kinetic model, fluid model, and hybrid model.

Kinetc description

The kinetc model is the most fundamental model to describe a plasma, resultantly producing a distribution function f(x, v), where independent variables x and v are position and velocity, respectively.

A kinetic description can be achieved either by solving the Boltzmann equation or tracking individual particles (called particle simulation).

Fluid description

To reduce the complexities in the kinetic description, the fluid model solves the equations for macroscopic quantities such as density, momentum, and energy, moments of the distribution averaged over the presumed distribution function.

Hybrid model

The hybrid model is a combination of fluid and kinetic models.
