Presidential Young Investigator Award: Theoretical And Computational Fluid Mechanics

本研究将集中于涡旋动力学，包括涡旋运动的基本问题和计算方法的发展。理论工作涉及涡旋运动的非线性动力学描述，如混沌和孤子。计算工作包括开发有效的基于涡的算法和代码，用于跟踪统计上不断演变的流，包括剪切层、尾迹和分层流中的界面。将研究结果应用于涡度主导的流动，例如螺旋桨叶片的涡脱落、声音和噪声产生以及剪切层中的相干结构。

This research will focus on vortex dynamics including fundamental issues of vortex motion and the development of computational methods. The theoretical work is concerned with nonlinear dynamics description of vortex motion, such as chaos and solitons. The computational work involves development of efficient vortex-based algorithms and codes for following statistically evolving flows including shear layers, wakes, and interfaces in stratified flows. Application of the results to vorticity dominated flows will be pursued, e.g. vortex shedding from propeller blades, sound and noise production, and coherent structure in shear layers.
