摘要
全拉格朗日、无网格光滑粒子流体动力学(Smoothed Particle Hydrodynamics,SPH)不仅在理论上取得了巨大进步,也在科学与工程领域拓展了应用范围.本文简要综述了SPH方法及其在流固耦合建模领域的最新进展,包括:(1)基础理论与核函数修正;(2)基于黎曼求解的Riemann-SPH方法及耗散控制;(3)Total Lagrangian SPH(TL-SPH)方法及其稳定格式;(4)流固耦合的数值方法以及多分辨率离散.
The full Lagrangian meshless smoothed particle hydrodynamics(SPH)method has experienced a tremendous enhancement in methodology and has played a key role in a range of scientific and industrial applications involving complex multi-physics systems.This paper presents a concise survey of the SPH method and its applications in fluidstructure interaction(FSI),including(1)theory and fundamental with kernel corrections;(2)the Riemann-SPH method and dissipation limiting scheme;(3)total Lagrangian formulation with the stabilized scheme;(4)FSI scheme with interface treatments,and multi-resolution scheme.
