Detailed Description

Class used to implement an approximate impurity line radiative cooling model.

For warpy class see warpy.apps.mhd.radiation.radiation.impurity_line

Approximates cooling rate \(L_z\) by three-part piecewise exponential function of \(T_e\)

\begin{align*} L_z = \left\{ \begin{matrix} T^{m_1} \times 10^{b_1}, & T < T_1 \\ L_{z0}, & T \le T_1 \; \text{and} \; T \ge T_2\\ T^{m_2} \times 10^{b_2}, & T > T_2 \end{matrix} \right. \end{align*}

Collisional effects are incorporated through a multiplicaiton factor \(f_{cor}\) where

\begin{align*} f_{cor} = \left\{ \begin{matrix} 1, & n_z \tau_z \le (n\tau)_{roll} \\ C (n\tau)_{roll} (n_z \tau_z)^{-1}, & n_z * \tau_z > (n\tau)_{roll} \end{matrix} \right. \end{align*}
