Findings

Accurately simulates shock waves in crystalline polymers

Demonstrates the model's quantitative agreement with experimental data

Lays groundwork for reduced detonation wave models

Abstract

We present a model of mesoparticles, very much in the Dissipative Particle Dynamics spirit, in which a molecule is replaced by a particle with an internal thermodynamic degree of freedom (temperature or energy). The model is shown to give quantitavely accurate results for the simulation of shock waves in a crystalline polymer, and opens the way to a reduced model of detonation waves.
