International Conference Center, Waseda University), Shinjuku-ku, Tokyo, Japan, Numerical simulations with a high-resolution computational scheme are conducted to investigate the three-dimensional flow around a plunging and pitching wing. The figure-eight wing motion is considered based on observations of the hovering flight of bumblebee Bombus terrestris. The Reynolds number is 8800 and Mach number is 0.0485 based on the chord length and the maximum translational velocity of the wing. Fluid dynamics, aerodynamic force generation, and sound generation are analyzed and discussed. Computed results indicate that most of the aerodynamic forces are generated in the transverse motion of the wing due to the downwash and the production of the leading-and trailing-edge vortices. It is found that the generation of the dipole-like vortical structure and the interaction between the leading- and trailing-edge separated shear layers seem to be main source of the sound generated from the plunging and pitching wing., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1930011018, レポート番号: JAXA-SP-19-007},
