内容記述 | The instability of axisymmetric laminar wake behind a body of revolution whose cross section is a NACA0018 airfoil is studied experimentally under a natural disturbance condition. Magnetic Suspension and Balance Systems (MSBS) are used to support the axisymmetric body in order to avoid undesirable influences of mechanical supports on the disturbance development. A multi-hotwire-sensor probe is used to identify helical instability modes. The experiment is conducted mainly at a Reynolds number based on the maximum diameter Re = 1.9 × 10(exp 4). It is found that the wake is convectively unstable despite that the flow is slightly reversed near the trailing edge. Spatially-growing instability waves are found to be helical modes with azimuthal wavenumber of 1 as predicted by the linear stability theory for the axisymmetric wake. The spatial growth rate and amplitude distribution obtained experimentally agree well with those calculated from the linear stability theory. | |||||
