| 摘要: |
| 光滑粒子流体动力学(smoothed particle hydrodynamics, SPH)是实现流体仿真的主要技术之一. 随着生产实践中流体仿真应用需求的增加, 近些年涌现了许多相关研究成果, 改善了流体不可压缩性、粘性、表面张力等物理特性模拟的视觉真实性、效率与稳定性. 同时, 一些工作探讨了复杂场景的高质量模拟, 以及多场景、多材料的统一仿真框架, 增强了SPH流体仿真技术的应用效能. 从以上几个方面对SPH流体仿真技术进行归纳、总结和讨论, 并对其未来发展进行了展望. |

| Abstract: |
| Smoothed particle hydrodynamics (SPH) is one key technology for fluid simulation. With the growing demand for applications of SPH fluid simulation technology in production practices, many relevant studies have emerged in recent years, which improve the visual authenticity, efficiency, and stability simulated by physical properties including fluid incompressibility, viscosity, and surface tension. Additionally, some researchers focus on high-quality simulation in complex scenarios and a unified simulation framework with multiple scenarios and materials, thereby enhancing the application efficiency of SPH fluid simulation technology. This study discusses and summarizes related research on SPH fluid simulation technology from the above aspects, and proposes a prospect for the technology. |
