The estimation of absorption coefficient of the lightning coaxial unification fractal model from the particle point of view

This paper tries to estimate the absorption coefficient of the lightning coaxial unification fractal model (CUFM) from the particle point of view. Firstly, the lightning channel ionization and dissociation transitions have been studied. Secondly, by the Braginskii formula and the velocity current fractal relationship, the object function of the kappa coefficient and core radius is established. Finally, the numerical simulation of the absorption coefficients is accomplished by optimizing and minimizing the object function. It is found that the kappa outcomes are basically consistent with the past CUFM adopted method.
