论文摘要
本工作的目的是对翼尖涡流的形成及其与周围流动的相互作用进行系统研究，以提供更多细节。特别有趣的是这些涡流与壁湍流和湍流唤醒的相互作用。这是通过考虑两个机翼几何形状，即无限跨度（周期性）和三维（机翼）翅膀，以三个不同的攻击角度来完成：$α= 0^o $，$ 5^o $，$ 10^o $。模拟由高阶不可压缩的Navier-Stokes求解器NEK5000进行，并增加了KTH的自适应网格细化（AMR）功能。
The goal of the present work is to perform a systematic study of the formation of wing-tip vortices and their interaction with and impact on the surrounding flow in more details. Of particular interest is the interaction of these vortices with wall turbulence and the turbulent wake. This is done by considering two wing geometries, i.e., infinite-span (periodic) and three-dimensional (wing-tip) wings, at three different angles of attack: $α=0^o$, $5^o$, $10^o$. Simulations are performed by the high-order incompressible Navier-Stokes solver Nek5000 with added adaptive mesh refinement (AMR) capabilities developed at KTH.
