Compressible Vortex Dynamics and Turbulence: Reconnection, Core Dynamics, and Fine-Scale Organization

直接数值模拟（DNS）将在一个 压缩性对几种涡的影响研究 湍流剪切流中的动力学现象。这项研究是 重点研究涡旋重联、涡旋核心动力学以及 有组织的涡流结构之间的相互作用， 混乱的背景湍流。的一个新颖特征 研究是分析初始条件对 数值可压缩流 仿真。 这一研究对高速流动技术 和 模拟这些和其他湍流的技术 在数值上具有更高的准确性和经济性。

Direct Numerical Simulation (DNS) will be carried out in a study of the effect of compressibility on several vortex dynamics phenomena in turbulent shear flow. The study is focused on vortex reconnection, vortex core dynamics, and the interaction between organized vortex structures and disorganized background turbulence. A novel feature of the research is an analysis of the effect of initial condition on numerical compressible flow simulations. This research impacts both the technology of high speed flows and the technology of simulating these and other turbulent flows numerically with greater accuracy and economy.
