Tube, Vector


the set of all vector lines of a vector field that pass through some closed curve (seeFIELD THEORY). With every vector field is associated the vector field of its curl. The vector tubes of a vorticity field are called the field’s vortex tubes. The vortex flux through any cross sections of a vortex tube is constant and is called the strength of the vortex tube.
