Expansions des Plasmas poussiéreux en géométrie sphérique

Abstract : Plasma expansion has get many interrest this last decade, especially after the recent observation in astrophyical plasma as well as in laboratories plasma. The presence of dust in plasma change the caracteristic of the plasma and gives rise to a new effects not observed in plasma without dust. In this work, the plasma expansion with the presence of dust in spherical configuration is modeled using self similar formulation for different physical situation using ideal and non ideal cases. It is found that the self simlar solution is valid for finit value of self similar parameter. In the other hand a spike like structures where etablished for our cases which show the existence a wave front where the quasi neutral condition is not valid.
