摘要
复杂流动和流体行为中的多尺度结构对化学工程的理论和应用研究都是巨大的挑战。多尺度的粒子模拟是处理复杂界面、物性以及连续介质模型难以适用的纳微和极端条件下流动的有力手段之一。本文将重点介绍本实验室近年来以拟颗粒模拟为基础的微观粒子模拟研究及其在流态化和纳微流动中的应用,并在此基础上探索离散模拟通用化的可行性。
The multi-scale structures of complex fluid flows and behaviors present great challenges to the theoretical foundations and applications of chemical engineering. Multi-scale particle methods are among the promising choices for the simulation of systems with complex phase interfaces, extreme material properties, and nano/micro-flows where continuum models are not readily applicable. The researches carried out in our lab on micro-scale simulations using pseudo-particle modeling are reviewed in this article. The application of the model has focused on gas-solid fluidization and nano/micro-flows.
