    Abstract
  • Given the mono-temperature model and tri-temperature model as the two radiation-magneto-hydrodynamic models in the physical process of the Z-pinch, it is useful to understand the difference between the two models for a better use of these tools.In this paper the difference between the two models in the process of modeling is explained and three calculating models are designed to study the calculation difference resulting from the two models.The simulation results achieved show that the tri-temperature model has a faster spindle-touching speed, which is more obvious in low-temperature and heavy loads.The research by taking into account the physical reality shows that the difference between the two models is mainly caused by the equation of state (EOS):at low temperatures, there is a significant difference between atomic EOS and ionic EOS, hence the loaded surface has an uneven inflation, which eventually leads to the difference of the received kinetic energy; at high temperatures, this difference is reduced.Moreover, the EOS makes it more apt for impulse waves to be formed in the tri-temperature program than in the mono-temperature program and for the pioneering plasma to be formed as well.However, the calculation difference caused by the kinetic energy plays a major role.
