lir_achem.compute_collision_frequency

There are two main functions in this module, to compute the electron-ion collision frequency and the electron-neutral one

Functions

ei_collisionfreq(e_here, i_here)	Computes the collision frequency between the electrons and one ion species From Schunk & Nagy (1978) and Zawdie et al., 2017 We suppose that electrons, ions and neutrals have the same temperature
en_collisionfreq(e_here, n_here)	Computes electron-neutrals collision frequency From Schunk & Nagy (1978) and Zawdie et al. (2017).

lir_achem.compute_collision_frequency.ei_collisionfreq(e_here, i_here)

Computes the collision frequency between the electrons and one ion species From Schunk & Nagy (1978) and Zawdie et al., 2017 We suppose that electrons, ions and neutrals have the same temperature

Parameters:

• e_here – Electron class instance

• i_here – Ion class instance

Returns:

v, collision frequency (s-1)

lir_achem.compute_collision_frequency.en_collisionfreq(e_here, n_here)

Computes electron-neutrals collision frequency From Schunk & Nagy (1978) and Zawdie et al. (2017)

Parameters:

• e_here – Electrons class instance

• n_here – Neutrals class instance

Returns:

v, collision frequency (s-1)
