Arbitrary Lagrangian-Eulerian discrete velocity method with application to laser-induced plume expansion

作者：

Highlights：

• A direct arbitrary Lagrangian-Eulerian discrete velocity method is proposed.

• Results are obtained by solving numerically the BGK model kinetic equation.

• Cross-comparison with DSMC results are provided.

• A two-order of magnitude acceleration as compared to traditional schemes is demonstrated.

• Kinetic code scalability for up to 10752 cores is shown.
