vortex line meaning in Hindi

Examples

1. A vortex tube whose vortex lines are all closed will be a closed torus-like surface.
2. A newly created vortex will promptly extend and bend so as to eliminate any open-ended vortex lines.
3. In the 1950s, Hall and Vinen performed experiments establishing the existence of quantized vortex lines in superfluid helium.
4. In the superfluid component, however, vorticity is restricted to the quantized vortex lines, and there is no viscous dissipation.
5. This field then penetrates the superconductor as a lattice of " vortex lines " that define the superconductor's electronic behavior.
6. In turbulence, the vortex lines arrange themselves in an irregular fashion, and this is described as a " vortex tangle ".
7. When a vortex line ends at a boundary surface, the reduced pressure may also draw matter from that surface into the core.
8. In general, vortex lines ( in particular, the axis line ) are either closed loops or end at the boundary of the fluid.
9. One end of the vortex line is attached to the engine, while the other end usually stretches out and bends until it reaches the ground.
10. According to Helmholtz's theorems, a vortex line cannot start or end in the fluid  except momentarily, in non-steady flow, while the vortex is forming or dissipating.
