A model of corona sheath that surrounds the
thin core of the lightning channel has been investigated by
using a new space charge function. The lightning channel
is modeled by a charged corona sheath that stretches
around a highly conductive central core through which the
main current flows. The channel core with the negatively
charged outer channel sheath forms a strong electric field,
with an overall radial orientation. The return stroke
process is modeled as the negative leader charge in the
corona sheath being discharged by the positive charge
coming from the channel core. The corona sheath model
[1-5], divides the sheath onto two zones with charges: zone
1 (surrounding the channel core with net positive charge)
and zone 2 (surrounding zone 1 with negative charge). We
introduced a new expression of the space charge
distribution inside both zones that represents the
generalization of the previously used space charges. Using
certain values of the parameters one can ...get the previously
examined corona charge densities as the special cases of
this generalized distribution. Simultaneously, the influence
of the new distribution of the space charge on the corona
sheath dynamics is examined. Expressions that describe
how the corona sheath radius evolves during the return
stroke are obtained from the accepted corona sheath
model and the new sheath space charge density. The new
distribution can be easily applied in the transmission-linetype
of models as well.
