摘要
本文研究了单次扇形冰吸积和两次低保真冰形模拟的气动效应。将这些数据与雷诺数为1.6 x 10.6的干净的8.9%比例CRM65半跨翼模型的空气动力学进行了比较。干净的机翼经历了猛烈的、尖端优先的失速,在较低的迎角处出现了一个小而强的前缘涡,而结冰的机翼在相同的迎角下出现了更大、似乎较弱的前缘涡。对于低保真度的冰形,这些漩涡的大小更大。的
Effect of Simulated Scalloped Ice on the Aerodynamics of a Swept-Wing at Low-Reynolds Number
This paper studied the aerodynamic effects of a single scalloped ice accretion and two lower fidelity ice-shape simulations. These data were compared to the aerodynamics of a clean 8.9% scale CRM65 semispan wing model at a Reynolds number of 1.6 x 10 6 . The clean wing experienced an aggressive, tip-first stall and showed a small, strong leading-edge vortex at lower angle-of-attack while the iced cases showed larger, seemingly weaker leading-edge vortices at similar angles. The size of these vortices is larger for the low-fidelity ice shape. The
