Can a horizontal vortex of a fluid exist by strong suction?
Is it possible to create a horizontal vortex in a tubular flask, if the fluid is subjected to a strong suction?

Yes.. I'm sure if you google around a bit you'll find more, maybe behind airplanes, behind cars, fans? etc.
What is the picture for?

I'll be using this thread to ask more questions about the nature of vortices. Of particular interest is the nature of helical vortices. Anyone having
experience with this topic, please post. I need your insights.
Thank you,

Maybe I should have been more precise. I was speaking of the vortices that normally occur when a fluid drains from a tubular shaped container. I am
familiar with the other examples you've given here. But they don't apply.
That picture comes from this link:

Even more specifically, I mean a container of fluid laying on it's side. So that the liquid contained is forced to drain sideways.

I think it would be very hard to get a vortex to form that way in a horizontal arrangement. I would imagine it would have to be a VERY powerful
suction to overcome the asymmetrical force that gravity provides.. If it would work at all.

That's true!

But I'm wondering if the vacuum was very strong, if the vortex would be forced to present as a helical, specifically due to the asymmetrical
gravitational forces exerted.

I think the simple answer is, if vortices occur in the venturis of injectors, it would likely exist in a horizontal tube as well. Provided the suction
WAS strong enough.

No. Pictured is a gravity vortex. Vacuum at the bottom isn't so much to suck as to remove liquid once it gets there.

Are you using the word "Fluid" precisely or loosely? What I mean is are you interested only in liquids? or gases also?
Cyclone Separators are devices based on vortex principle. It is unusal to find horizontal Hydroclones (i.e. Liquid cyclones) but horizontal gas
cyclones are very common.

A liquid does not define all fluids. My bad!

It was only an example...

I only wanted to show what I meant. I know this vortex is caused by gravity. But I wanted to know if I apply a very strong suction to a rigid bottle,
would it be possible to lay the bottle on it's side and keep the vortex intact.
I specifically mean vacuum by use of a strong pump!

That horizontal vortex in what looks like water in a cylindrical glass jar (or similar) looks as if it was produced by the rotation of a magnet at its
bottom, caused by a laboratory magnetic stirrer. A very similar effect would be produced by filling the receptacle of a blender with water, and
turning it on.
At least one of the books on Fluid Mechanics - that by White - and one of the Coulson & Richardson volumes, which I have uploaded, and the
downloading links for which I have given in the Chemical Engineering books thread in the References section, should explain the fluid mechanics of
vortices. I think that Streeter's Fluid Mechanics is also available as an ebook. To find links for the latter, look up the following search string on
Google: Streeter "fluid mechanics" "rapidshare.com/files" PDF OR ZIP OR RAR OR DJVU

No magnetic personalities here!

See this link for how this vortex was created:

Would you please give the links that you've mentioned above? Thank you!
