Theoretical and experimental efforts to describe the expansion of laser-induced plasma plume are reviewed. Particular attention has been devoted to a comparison between experimental and theoretical time of flight (TOF) profiles. The theoretical results obtained by inserting plasma kinetics in one-dimensional fluid-dynamic code show that chemical processes strongly influence the fluid dynamic expansion. Moreover fluid-dynamics codes based on both Navier-Stokes and DSMC models, which in addition include the possibility of different temperatures for electrons and heavy particles, are discussed.

Abstract
Theoretical and experimental efforts to describe the expansion of laser-induced plasma plume are reviewed. Particular attention has been devoted to a comparison between experimental and theoretical time of flight (TOF) profiles. The theoretical results obtained by inserting plasma kinetics in one-dimensional fluid-dynamic code show that chemical processes strongly influence the fluid dynamic expansion. Moreover fluid-dynamics codes based on both Navier-Stokes and DSMC models, which in addition include the possibility of different temperatures for electrons and heavy particles, are discussed.File in questo prodotto:
