Abstract: 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.

Key words: simulation, fluid mechanics, smoothed particle hydrodynamics, two-phase flow, non-Newtonian fluids, fluid-structure interaction, mesh-less method
