粒子是构成物质的基本单元，基于粒子的计算方法是模拟简单乃至复杂介质的一个自然选择，也被广泛视为新一代计算方法，在研究多相、多尺度、多物理场等复杂问题方面具有特殊优势。该书从微观尺度、介观尺度到宏观尺度介绍了分子动力学（molecular dynamics，MD）、耗散粒子动力学(dissipative particle dynamics，DPD)以及光滑粒子动力学（smoothed particle hydrodynamics，SPH)等三种粒子类方法的基本理论、数值方法及内在联系。该书也结合刘谋斌研究员及合作者多年的研究工作，阐述了相关粒子方法的一些最新理论模型与数值方法，并给出了科学与工程领域的众多应用，包括微流动和生物流动（微液滴动力行为、高分子悬浮与输运、细胞变形、粘附与运移等），环境与地质流动（多孔介质与裂隙网络中多相流动、溃坝、泥石流等），自由液面流动（波浪砰击、液体晃荡、结构出入水、溢油拦截等）。该书所展示的理论模型、数值方法及示范案例将有助于推动粒子类数值方法与应用方面的研究工作。
Multi-scale and multi-physics modeling is useful and important for all areas in engineering and sciences. Particle Methods for Multi-Scale and Multi-Physics systematically addresses some major particle methods for modeling multi-scale and multi-physical problems in engineering and sciences. It contains different particle methods from atomistic scales to continuum scales, with emphasis on molecular dynamics (MD), dissipative particle dynamics (DPD) and smoothed particle hydrodynamics (SPH).
This book covers the theoretical background, numerical techniques and many interesting applications of the particle methods discussed in this text, especially in: micro-fluidics and bio-fluidics (e.g., micro drop dynamics, movement and suspension of macro-molecules, cell deformation and migration); environmental and geophysical flows (e.g., saturated and unsaturated flows in porous media and fractures); and free surface flows with possible interacting solid objects (e.g., wave impact, liquid sloshing, water entry and exit, oil spill and boom movement). The presented methodologies, techniques and example applications will benefit students, researchers and professionals in computational engineering and sciences.
Mou-Bin Liureceived his B E and M E degrees from Xi'an JiaoTong University (XJTU), China, in 1993 and 1996, respectively, and received his PhD from the National University of Singapore (NUS) in 2003. He is currently a professor at the College of Engineering and the Institute of Ocean Research of Peking University. He has authored more than 100 reviewed technical papers and one monograph, with more than 2000 SCI citations. He has received a number of prestigious awards from universities and scientific organizations worldwide, including the100 Talent Program Awardfrom the Chinese Academy of Sciences (CAS) in 2009, theYoung Investigator Awardfrom the Asia Pacific Association of Computational Mechanics (APACM) in 2007 and theLee Kuan Yew Fellow Awardfrom Nanyang Technological University (NTU), Singapore, in 2005. He is interested in computer modeling of complex flows with different coupling effects, and has developed some original numerical methods, both grid-based and meshfree particle-based, for modeling fluid dynamics and fluid-solid interactions, including high energy explosive detonation and explosion, underwater explosion, high strain hydrodynamics with material strength, wave breaking and interaction with structures (e.g., sloshing and slamming), and water entry and exit.
