作者： Rui Yuan Hui-yun Hao Qin wu Yun-qing Liu Biao Huang School of Mechanical Engineering Beijing Institute of TechnologyBeijing100081China

The objective is to study the vortical structural behaviors of a transient pitching hydrofoil and their effects on the hydrodynamic performance. The pitching motion of the hydrofoil is set to pitch up with an almost constant rate from 5° to 15° and then back to 5°, with the Reynolds number 4.4×10^(5) and the frequency 2 Hz. The results show that the main coherent structures around the pitching hydrofoil include small-scale laminar separation bubble (LSB), large-scale second vortex (SV) and trailing edge vortex (TEV) which are all vortical. The relationship between the vortical structure and the lift is investigated with the finite-domain impulse theory. It indicates that the major part of the lift is contributed by the LSB, whereas the shedding and the formation of the SV and TEV cause the fluctuation of the lift. The proper orthogonal decomposition (POD) method is applied to capture the most energetic modes, revealing that the LSB mode occupies a large amount of energy in the flow field. The dynamic mode decomposition (DMD) method accurately extracts the dominant frequency and modal characteristics, with the first mode corresponding to the mean flow, the second mode corresponding to the LSB structure and the third and fourth modes corresponding to the vortex shedding.

自从电影《丝路花雨》以来,我国大约有四十年没有出现过有影响力的艺术舞蹈电影了。无论是从我国艺术舞蹈电影历史来看,还是同海外艺术舞蹈电影发展的比较来看,艺术舞蹈电影缺席我国电影发展,尤其是缺席近二十年中国电影的高速发展的历史,都是值得人们反思的。影响我国艺术舞蹈电影发展的原因固然很多,但艺术舞蹈电影的文化工程式的生产制作方式、艺术舞蹈电影的类型化探索不足、市场对于艺术舞蹈电影信心不足等,则是应该引起人们关注、并加以重点解决的问题。
