光滑粒子流体动力学（SPH）是一种拉格朗日、无网格的粒子方法，在工程和科学的各个领域得到了广泛的应用。自Monaghan于1994年将SPH扩展到自由表面流动模拟以来，SPH已逐渐发展成为粘性不可压缩流体流动模拟的一种有吸引力的方法。本文从与SPH模拟计算精度密切相关的四个主要方面综述了SPH在粘性不可压缩流动模拟中的最新进展。分析了SPH粒子近似方法、压力场求解方法、固体边界处理算法和粒子自适应算法的优缺点。讨论了粘性不可压缩流动SPH模拟的一些新的观点和未来的发展趋势。
Smoothed particle hydrodynamics (SPH) is a Lagrangian, meshfree particle method and has been widely applied to different areas in engineering and science. Since its original extension to modeling free surface flows by Monaghan in 1994, SPH has been gradually developed into an attractive approach for modeling viscous incompressible fluid flows. This paper presents an overview on the recent progresses of SPH in modeling viscous incompressible flows in four major aspects which are closely related to the computational accuracy of SPH simulations. The advantages and disadvantages of different SPH particle approximation schemes, pressure field solution approaches, solid boundary treatment algorithms and particle adapting algorithms are described and analyzed. Some new perspectives and future trends in SPH modeling of viscous incompressible flows are discussed.
