Toyama International Conference Center), Toyama Japan, It is important to realize the unsteady aerodynamics of the wing in relation to the flow field around it　in low Reynolds number flow. In this study, the numerical analysis of the two-dimensional flow around a corrugated wing section at Reynolds number 10,000 is carried out. The calculated lift coefficient shows unsteady behavior, depending on the angle of attack. In the case of zero angle of attack, the calculated lift coefficient shows almost steady behavior as well as periodic oscillation. However, the strong unsteadiness is shown in the cases of large angle of attack. The chaotic feature of its unsteadiness is analyzed by the spectral analysis and the attractor reconstruction technique using the time-delay coordinate, as well as the phase-plane plot. As a result, the spectral distributions in the cases of large angle of attack are closely similar to the distribution of the Brownian noise. The observation of the flow field indicates that s""" uch feature is closely related to the periodic or non-periodic motion of the separated vortices over the corrugated wing section. More advanced, essential realization of the obtained spectral distributions similar to of the Brownian noise should be clarified with additional researches., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0061958039, レポート番号: JAXA-SP-12-010},
