TOPOLOGICAL STRUCTURES OF VORTEX AND HELICITY ANALYSIS

In this paper,we discuss the topological structures of the vortexfilaments and vortex tubes with an exact solution of a straight spiral vortex tube.We find that there are some confusions about the calculation of the helicities of aknotted vortex filament and some linked vortex filaments by using dif...

Zusammenfassung:In this paper,we discuss the topological structures of the vortexfilaments and vortex tubes with an exact solution of a straight spiral vortex tube.We find that there are some confusions about the calculation of the helicities of aknotted vortex filament and some linked vortex filaments by using different methods.We explain how to unify these methods and give the right results.
