A fluid exiting from a pressurized tank by a circular aperture should
have a cylindical shape in 0 gravity and vaccum conditions. I don>t
know much of fluid mechanics and I would like to know the equations of
such a situation to compare them with these of a soliton propagation
in optics.
At the exit of the tank, there should be "diffraction" of the flow,
and this diffraction should be compensated by the surface tension.
This is exactly the same in optics where the diffraction if
compensated by a self-focusing mechanism. I that case, the refractive
index depends on the intensity. Then, if you have au gaussian
intensity profile you induce a refractive index distribution similar
to a lens.
If someone can help me and tell me where I can find these
informations...
Thanks. |

Any fluid in a vacuum would boil.

Please don>t let the mercury in my McLeod gauge know about that....
