Instabilities in Trailing Vortices: Flow Visualization Using Hot-Wire Anemometry,
Abstract
It is noted that trailing vortices often break up after the formation of disc shaped disturbances. Reference is made to a flow visualization experiment performed by Fackrell in which similar strongly dissipative disturbances were produced in the laboratory. Details of the origin and development of this instability are discussed. To obtain quantitative information on this phenomena and experiment using hot wire anemometry and a conditional sampling technique was set up. Data are presented on a solitary wave-like disturbance which was found on the outer edge of the core and convected downstream at about disturbance is not axi-symmetric. (Author)
