摘要

A two-dimensional molecular dynamics simulation was performed to investigate the propagation behavior of an initial thermal perturbations in the liquid argon. The model includes 3000 (150 x 20 ) rigid particles. The 12-6 Lennard-Jones potential was used to describe interactions among argon particles. Simulation results demonstrated that the heat was transported always by diffusion, and no wave phenomena such wave as front and wave reflection were observed, even at early time of fast transient heat transfer process. A fast, large thermal perturbation propagated in part by diffusion and in part by wave. The latter was always associated with the pressure wave and not related to the heat wave in the sense of C-V model.
