| 摘 要： | 从实验和数值模拟两方面评述了颗粒-湍流拟序结构相互作用的近期研究进展.关于Stokes数不同对颗粒行为和拟序结构影响的试验研究,从单点激光多普勒测量到粒子图像全场测速,并与流场显示定性方法结合,揭示了不同Stokes数范围颗粒-拟序结构相互作用的规律.基于涡方法、直接数值模拟和大涡模拟等的模拟研究,进一步揭示颗粒-拟序结构的相互耦合作用和外界激励的调制作用等规律,同时推动了算法的发展.

| Abstract: | Reviews are conducted on the progresses for the particle-vortex interactions in two-phase free shear turbulent flows, including jets, mixing layers, bluff-body wake flows etc. Experiments and numerical work on the topic are summarized. The flow visualizations, improved LDA and PDA diagnostic, the digital particle image velocimetry and other experimental techniques are compared. Simulations by vortex method, large-eddy simulation, direct numerical simulation are also discussed. |

| Keywords: | two-phase flow particle-vortex interaction coherent structures flow visualization numerical simulation |
