Paper Abstract

In this work we present a theoretical study concerning the Laser Induced Breakdown Spectroscopy (LIBS) in water. A 1D Euler code has been developed and coupled with a complete kinetic model. This study has been applied to the evaporation of a titanium target in water. The strong influence of chemical processes on the fluid dynamic expansion has been shown. Moreover the introduction of two pulses, which is a typically experimental approach in water, has been simulated. The effect of the second pulse on the macroscopic quantities has been deeply discussed.
