Interaction of two ring vortices with different translation axis and formation of new ring vortices from an oscillating ring vortex
Abstract
The merging, overtaking, and diffusion of two interacting ring vortices, successively formed at the same circular nozzle where the initial translational axis breaks down, is described. The same processes are studied for vortices meeting obliquely. The formation of new ring vortices from one vortex originating from nozzles of various shapes is explained. Photographic techniques using dyes in water were utilized.
