Vortex Definition and 121 Threads

Hi, I have a small confusion regarding using the terms "vortex and eddy". My doubt is 'what is vortex and eddy?' 'where are this terms appropriate to be used?' 'what is the difference between them?' may be this is silly question but if anyone can help I would thanks him in advance.

my question relates to the axisymmetrical ring vortex. i know that vorticity must remain constant within a tube, (helmholtz vortex theorem 2) so does that mean that the vortex lines on the outside of the ring are longer (spinning faster) than the ones on the inside? also is that what makes...

To anyone familiar with the Ranque-Hilsch vortex tube: Say if the cooled air is allowed to pass over the vortex section of this tube, what would happen? Would the effect of cooling be the destruction of the vortex? or would it act to further decrease the temperature of the cold exhaust?

Benefit of a "Vortex Generator" in a turbocharged automotive applications As the title states, What is, if any, benefit of creating a vortex in the air flow prior to it entering the turbocharger. Here is a photo of the "Vortex Generator" in question...

I hope someone can help with this - its been driving me mad for a while now! You will have noticed the shape coffee (or whatever liquid) takes when you stir it. Clearly a vortex getting deeper and steeper the faster it is stirred. So - here's my problem. What's the equation that defines...

Hello, below are some specs I was provided of a micro screw air compressor, its physical dimensions are 4x4x4 and it seems pretty impressive for its size. However I am trying to understand a few things about the data that was provided. I am provided 6 charts on power/airflow/psi etc, each...

Hi please explain the vortex flow the vortex flow properties the vortex flow Generation the vortex flow behaviour Ryan

Is there a way to calculate the rise in surface elevation of water in a vortex from the middle to the outside?

I recently invented a new application for vortex tube. The application requires a very minimal flow of air at freezing temperature. I wonder if it's possible to design a vortex tube at a very small size if only a very tiny air flow is required? Is flow rate proportional to physical size...

Hey folks... I am goin nuts with this vortex thing. please somebody help me pleasezzzzzzzzzzzzzz my doubts 1.whats bound vortex? 2.Whats horse shoe vortex? 3.Whats free and forced vortex? 4.Whats vortex tube? 5.Whats vortex filament? please give me some hints and any web sites if...

I was looking at this animation of vortex being shed by a cylinder http://ctr.stanford.edu/gallery/cyl3900.html and was wondering if the side to side periodic motion of the vortex is what causes a flag to fly in a wavy way on a pole?

have anybody heared about the vortex tube?its an air cooler tube without any moving parts,and there is a link where u can get a little info about it http://www.visi.com/~darus/hilsch/ my ques: 1-could the nozzle be straigh?(const cross section? 2-which materila i should use to design this...

I'm not sure where to ask this question. I suppose it's a fluid dynamics question, a field I don't know well. I saw a show on one of the science channels a while back where it was postulated that huge holes where cut in solid rock beds in the path of a flood which was apparently the volume...

Hi, Can anybody tell me where I can find the complete derivation of the vortex panel method (book / webpage)? It's easy enough to see where the fundamental equation comes from, but completing the integration etc. to get it in the form of influence coefficients is beyond me. I have the...

Hi all, I have a dumb question on the field inside of a vortex. A simple claculation using the magnetic flux quantum and estimating the vortex size to be 10-35nm. You get a magnetic field value of ~6.5-0.3 T. Which at first thought seems strange, maybe I'm not thinking of something correctly...

In the vortex panel method the following equation is used V_{freestream}sin \beta_i - \sum_{j=1}^n \displaystyle\frac{\lambda_i}{2\pi} \int \displaystyle\frac{d\theta_{ij}}{dn_i} ds_j = 0 where n is the panel number, i is the control point at which the vortex strength is being calculated...

tell me I am wrong " SEMI-INVERTED VORTEX " I have discovered a third vortex which explains the strange products and behaviours of atoms, stars and galaxy's, I am not an academic, but i would really like to discuss this with anyone, especialy if they know what their talking about

I am doing an investigation into the air flow from a fan in my physics class. I need to know why the reason why air flows in a vortex shape from the fan (in physics terms), and what equations I can investigate (anything, e.g thrust etc). Also, I believe the airflow from a fan can be...

does anyone know what's breakdown of a vortex. what is its significance in airplane design?

vortex ionisation Could you sustain a vortex in a vessel of water by ionising the water with high voltage ? Thanks, hope this question makes sense.

Care to share? They are claiming relativity is based on some wrong assumptions about time, that its obsolete.
