| Abstract: | A class of exact general solutions of an axisymmetric flow of the fluid dynamic equations is given. Then some examples are discussed. Some vortex solutions can be superposed to give other exact solutions. It can be used to analyse the generation and evolution of the vortex ring. |
| Keywords: | vortex elements spherical vortices cylindrical vortices superposition symmetry |
