The Two-Fluid Model

  • D. A. Frank-Kamenetskii


In the conducting-fluid approximation the current density is found from Ohm’s law, which is not very accurate for a plasma. A more detailed description of the electric currents in a plasma is given by the two-fluid model, the two fluids being the electrons and the ions. The motion of each of these species is described by the usual hydrodynamic equations which as we have seen are known as the hydrodynamic approximation, in contrast with the more accurate physical kinetics description.
