Název v původním jazyce

Nonlocal transport hydrodynamic model for laser heated plasmas

Popis výsledku v původním jazyce

The interaction of lasers with plasmas, whether pre-formed or due to ablation processes, very often takes place under nonlocal transport conditions. The nonlocality affects the transport of particles, mostly electrons, as much as it does radiation. In this study, the nonlocal transport is investigated for the plasma corona generated due to the deposition of laser energy. The nonlocal theory of the energy transport in radiative plasmas of the arbitrary ratio of the characteristic spatial scale length to the photon and electron mean free paths is applied to define closure relations of the hydrodynamic system. The corresponding transport phenomena cannot be described accurately with the usual fluid approach dealing only with local values and derivatives. Thus, the usual diffusive energy flux is instead calculated directly by solving a simplified transport equation allowing one to take into account the effect of long-range particle transport.
