内容記述 | We researched the fluctuating flow on the three types airfoils in the transition region of Reynolds number. The visual technique with the video recorder was used. It was found that the core of the wake vortex was clear at the low Reynolds number (Re=5450), but not clear at the high Reynolds number (Re=26900), because of the dissipation of the shear flow just before the wake vortex rolling up. And the width of the dead air region was one of the important parameters for generating the wake vortices (Karmman Vortex) so that the wide width of it made the wake vortex roll up near the trailing edge of the blade, but the narrow width of it made at far downstream of the blade. The position of the rolling-up vortex tended to the trailing edge at the high Reynolds number because the fluctuation of the shear layer increased. When the wake vortex rolled up from the shear layer directly near the trailing edge, not from the wake after the both side shear layers going together, the fluctuating flow on the blade was occurred. | |||||
