Abstract

This study proposes a model based on the combination of Smoothed Particle Hydrodynamics, Coarse Grained Molecular Dynamics and the Discrete Element Method for the simulation of dispersed solid-liquid flows. The model can deal with a large variety of particle types (non-spherical, elastic, breakable, melting, solidifying, swelling), flow conditions (confined, free-surface, microscopic), and scales (from microns to meters). Various examples, ranging from biological fluids to lava flows, are simulated and discussed. In all cases, the model captures the most important features of the flow.

摘要

本研究提出了一种基于光滑粒子流体动力学、粗粒化分子动力学和离散元方法相结合的模型，用于模拟分散的固液流动。该模型可以处理多种颗粒类型（非球形、弹性、可破碎、熔化、凝固、膨胀）、流动条件（受限、自由表面、微观）和尺度（从微米到米）。模拟并讨论了从生物流体到熔岩流等各种示例。在所有情况下，该模型都能捕捉到流动的最重要特征。
