OK, so the tracer (smoke or steam) has a certain density so it takes a certain frequency to form these shapes just right? Does the "wind" need to be a certain speed too? where, exactly, does the smoke come from in this example? The reason I ask is I see this in nature, storms and high clouds, a lot and wonder how they form. It's very interesting and beautiful.

@Landotter1 think of the time and space as a fluid and help unlock unlimited abundance re:"zero point energy" love,peace and enlightenment to all...good night and good luck.

Beautiful.

The relevant dimensionless number in this case is the Strouhal number (fD/V), you will obviously know the velocity of the moving fluid, the diameter of the cylinder, and the frequency of the vortices can be easily estimated, therefore you can calculate the Strouhal Number which is useful for scale - model testing, or in otherwords designing against these types of vibrations which can lead to both fatigue damage and noise (at suitable frequencies).

trippy...

boring! i need something i can win sci fair with

karman vortex shedding, i just did an AE lab on this in a wind tunnel. the vortices can develop a forcing function for the vibration of a wing.

the song is from chopin :

mazurka opus 68, number 2

[dfl6921]

the song is wonderful. Anyone know the name

[xlovenuggetx]

@dfl6921 shazam it.

[LboHans]

Nice... does anyone knows the name of the song? :D

[malkavianmind88]

if you find out the name of the song, would you mind passing it on to me?

[LboHans]

Yah sure, i still doesn't know but i will make u know when i do

[LboHans]

Try searching some Chopin's music, they are kinda similar, maybe its from Chopin Idk

It looks like a fish...

yay!!!

[iskranka]

Karman vortex street :) Thank you for the nice visualization :)

[RBChoman]

Excellent

[username9214]

j'adore ça .... éééhh la science !!

[joetke]

C'est beau effectivement. Mais le merveilleux c'est que cette mécanique trouve des applications dans différents domaines. J'ai un ami qui est chercheur dans les revêtements intérieurs de prothèses cardiaques et la mécanique des fluides est fortement sollicitée pour le "liquide" qu'est le sang.

Continuez de poster des vidéos comme celles-ci. Merci.
