摘要：

Neutral stability of Gortler vortices was experimentally and theoretically examined. By towing a concave wall of 500mm radius of curvature at a constant speed in a water tank, the neutral stability of the vortices in a low wavenumber region was experimentally determined by observing the behavior of a given disturbance, which was introduced with a row of wings of finite span, by the hydrogen bubble technique. The neutral curves were calculated for two cases of parallel flow and non-parallel flow models. The present measurements are explained by the Smith model better than by the Gortler model.
