内容記述 | The formation of a side jet in the initial region of a round jet is concerned with the wavy deformation of a vortex ring and a pair of streamwise vortices. These phenomena are difficult to investigate to be unstable, and the details are not clear. Therefore, this study aims to clarify the formation mechanism of side jets. To achieve this, we fixed the forming positions of the side jets by controlling both the wavy deformation of the vortex ring and the formation of streamwise vortices, using synthetic jets installed in a round nozzle. The following became clear from the controlled experiment and its numerical simulation. The side jets occur due to the secondary instability that develops in the braid region. The side jet is the flow induced outwardly in the radial direction by the circulations of a vortex ring and a pair of streamwise vortices. The apparently continuous flow of a side jet results from the periodic repetition of induced flow between vortex rings and the streamwise vortices. | |||||
