I had always understood that the root cause of the KH instability (as distinct from the the RT instab) was velocity shear NOT density difference. It is indeed the origin of the transition to turbulence in a sheared flow and of the instability of counter-current flow in a pipe. Both cases are straightforwardly analysed in the early pages of classic texts such as Chandrasekhar or Drazin & Reid.

Unless I get feedback telling me that I've got it totally round my neck, I shall move to edit this article accordingly. Linuxlad 19:26, 19 Apr 2005 (UTC)

Discrepancies between the description of Wavecloudsduval.jpg used on this page and on other pages

I've compiled a short list of discrepancies about this image at Image_talk:Wavecloudsduval.jpg. If someone really knows what this is, could you please fix the ambiguity and discrepancies between the pages? (I'd consider the discussion on the image's talk page to be the appropriate primary discussion place for this issue.) --Kaze0010 03:03, 29 June 2006 (UTC)[reply]

Oops

It appears that I put the guideline for the naming move on the wrong talk page, which caused it to not move with the page. Anyone know how to fix this? See Talk:Kelvin–Helmholtz instability. Dicklyon (talk) 00:57, 31 May 2008 (UTC)[reply]

I copy it to here:

En dash in name

Wikipedia:Manual_of_Style_(dashes)#Dashes says, "When naming an article, a hyphen is not used as a substitute for an en dash that properly belongs in the title, for example in Eye–hand span." So I moved it; it got moved back; I'll move it again. Dicklyon (talk) 00:53, 31 May 2008 (UTC)[reply]

File:Kelvin-Helmholtz Instability.ogv to appear as POTD soon

Hello! This is a note to let the editors of this article know that File:Kelvin-Helmholtz Instability.ogv will be appearing as picture of the day on March 26, 2012. You can view and edit the POTD blurb at Template:POTD/2012-03-26. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks! —howcheng {chat} 19:56, 23 March 2012 (UTC)[reply]

Picture of the day

A simulation of the Kelvin–Helmholtz instability, a phenomenon that can occur when velocity shear is present within a continuous fluid, or when there is sufficient velocity difference across the interface between two fluids. One example is wind blowing over a water surface, where the wind causes the relative motion between the water and air.Video: Bdubb12/Raeky

Vortex street?

Why is there an animation of a vortex street? 98.156.185.48 (talk) 21:07, 17 December 2023 (UTC)[reply]

Please see vortex street, it has some animations. Yodo9000 (talk) 20:11, 22 March 2024 (UTC)[reply]
