A. 通过模型跟踪流场光学测量与流场可视化，研究非定常运动物体相关流动问题，例如变速变攻角机动三角板的动态大尺度分离与再附规律，加减速运动圆柱绕流的尾迹滞后响应与特征结构演化规律等

B. 通过激光诱导荧光测量技术（PLIF），针对高施密特数剪切湍流中长期缺乏实验认知的问题，系统揭示了被动标量混合在结构组织、输运机制与间歇性方面的多尺度特征。研究表明，高施密特数条件下标量混合显著偏离经典被动标量理论，建立了跨“惯性–对流区”与“黏性–对流区”的统一实验图景。

C. 实验研究高聚物湍流结构及其自相似性：获得高聚物湍流临界层开尔文猫眼流线结构，其为湍流自维持关键结构；从高聚物湍流结构自相似性的角度研究弹性和惯性对高聚物湍流的影响规律。

D. 经典涡环相互穿越过程是研究四极子噪声重要原型问题；本实验工作通过时间解析PIV流场测量结合涡声理论研究初始条件对四极子发声强度的影响规律。

E. 通过PIV测速与Langevin方程理论分析发现湍流边界层中的流向涡并不是无序乱动，其遵循可量化的随机动力学规律：平板上像“布朗粒子；，曲壁则因曲率诱导产生定向漂移和超扩散。
