plasmapy.formulary.braginskii.ion_thermal_conductivity(T_e, n_e, T_i, n_i, ion, m_i=None, Z=None, B: Unit("T") = <Quantity 0. T>, model='Braginskii', field_orientation='parallel', mu=None, theta=None, coulomb_log_method='classical') -> Unit("W / (K m)")¶ Calculate the thermal conductivity for ions.
Notes
This is the classical plasma ions’ ability to conduct energy and heat, defined similarly to other materials. The result is a conductivity in units of W / m / K, so if you assume you know where the heat is flowing (temperature gradient, cross-sectional area) you can calculate the energy transport in Watts as conductivity * cross-sectional area * temperature gradient. In lab plasmas, typically the energy is flowing out of your high-temperature plasma to something else, like the walls of your device, and you are sad about this.
