摘要
光滑粒子动力学(smoothed particle hydrodynamics,SPH)是一种纯粹的拉格朗日型无网格数值方法,尤其在处理包含自由表面或多相运动界面的复杂流动问题方面具有独特优势。随着计算精度和稳定性等方面的不断完善,SPH方法已被广泛应用于科学和工程的众多领域。介绍了SPH基础理论的最新成果,重点分析了其在界面流、流固耦合、非牛顿流体等领域的研究进展,并对未来发展进行了展望。
As a fully mesh-less, Lagrangian numerical method, smoothed particle hydrodynamics （SPH） has notable advantages in problems of complex flows with free surface and/or moveable interface. With the improvement in its accuracy and stability, the SPH method has been extensively used in different areas of science and engineering. The recent advances in SPH fundamentals are presented, with emphasis on interfacial flows, fluid-structure interaction, and non-Newtonian fluids. Finally, future development of the SPH method is prospected
