Web22 Apr 2024 · The partially ionized plasmas are usually in non-equilibrium ionization state in a certain time period. When reconnection happens, ohmic heating increases the plasma … WebAbstract Partially ionized plasmas, such as the solar chromosphere, require a generalized Ohm’s law including the effects of ambipolar and Hall drift. While both describe transport processes that arise from the multifluid equations and are therefore of hyperbolic nature, they are often incorporated in models as a diffusive, i.e., parabolic process.
