本文研究了圆形前缘后掠翼布局的涡控流动物理和气动特性。这项研究是基于使用计算流体力学方法DLR TAU的数值模拟。目标构型为恒定展弦比、可变前缘轮廓和前缘后掠角的后掠翼。研究了前缘前缘半径恒定和变化时前缘涡流的开始，前缘迎角、前缘后掠角和前缘马赫数的影响。此外，还分析和评估了圆形前缘涡流分离附近的气动特性和特定的流动物理特性。本工作的目的是为后掠翼布局的物理特性的设计和评估做出贡献。此外，还将给出设计过程的灵敏度。另外，Curren.
The present work is investigating the vortex-dominated flow physics as well as the aerodynamic behavior of swept wing configurations with round leading edges. The research is based on numerical simulations using the computational fluid dynamics method DLR TAU. The target configurations are swept wings of constant aspect ratio, variable leading-edge contours, and leading-edge sweep angles. The work deals with the onset of the vortical flow at the leading edge for constant and variable leading-edge nose radii, the influence of the angle of attack, the leading-edge sweep, and the onflow Mach number. Furthermore, the aerodynamic behavior is analyzed and assessed, as well as the specific flow physics in the vicinity of the vortical flow separation at round leading edges. The objective of the present work is to provide a contribution for the design and assessment of the physical characteristics of swept wing configurations. Furthermore, sensitivities will be given for the design process. In addition, the curren...
