论文摘要
自成立以来，Lagrangian无网状平滑粒子流体动力学（SPH）方法在方法论方面具有巨大的增强，并影响了科学和工程中的一系列多物理应用。 本文对SPH方法的最新发展和成就进行了简要的审查，包括（1）对理论的简要回顾和内核校正的基本审查， （2）通过使用MUSCL，WENO和情绪方案，基于Riemann的SPH方法具有耗散限制和高阶数据重建， （3）通过粒子分类和有效的双标准时间步进方案搜索的粒子邻居， （4）带有稳定的动力学放松和沙漏控制方案的Lagrangian总配方， （5）通过接口处理和多分辨率离散的流体结构相互作用方案， （6）粒子松弛在网格和颗粒世代的新应用。 最后但并非最不重要的一点是，还提供了验证计算准确性，收敛性，鲁棒性和效率的基准测试。
Since its inception, the full Lagrangian meshless smoothed particle hydrodynamics (SPH) method has experienced a tremendous enhancement in methodology and impacted a range of multi-physics applications in science and engineering. The paper presents a concise review on latest developments and achievements of the SPH method, including (1) brief review of theory and fundamental with kernel corrections, (2) the Riemann-based SPH method with dissipation limiting and high-order data reconstruction by using MUSCL, WENO and MOOD schemes, (3) particle neighbor searching with particle sorting and efficient dual-criteria time stepping schemes, (4) total Lagrangian formulation with stablized, dynamics relaxation and hourglass control schemes, (5) fluid-structure interaction scheme with interface treatments and multi-resolution discretizations, (6) novel applications of particle relaxation for mesh and particle generations. Last but not least, benchmark tests for validating computational accuracy, convergence, robustness and efficiency are also supplied accordingly.
