Abstract
- The paper is devoted to the construction of the efficient numerical methods to solve model kinetic equations as applied to the pulsed laser ablation (evaporation) into vacuum. We briefly describe the general ALE-type discrete velocity method and outline the modifications required for the present study. Then, we compute a particular moderate-intensity flow using Nesvetay code and compare the results for time-of-flight distributions and average axial energies with those of the DSMC code LasInEx. An accurate calculation of these quantities involves integration of the velocity distribution function in very narrow conical parts of the molecular velocity space and therefore requires the usage of a specially constructed mixed-element unstructured velocity mesh. Good agreement confirms the robustness and accuracy of the proposed discrete velocity approach. [ABSTRACT FROM AUTHOR]
