Someone has vandalised this page by replacing 'fluid' with 'poo'. Is there someone who knows how to restore it to its previous version? 7/11/2006 - Lti

I thought it would be good to add that much study of convection also relates to motion of fluids such as water in solar energy and HVAC. --User:Jdpipe

This definition of convection as a heat transfer mechanism is archaic. It might be a natural physical phenomenon relying on gravitation but it is no more a heat transfer mechanism than picking up a red hot poker and plunging into a bath of cold water.

It might be more useful today to relate this process to efficiency. For example forced convection is quicker than natural convection, a heatpipe can tanfer more heat for a given volume etc. Transfer through use of Latent Heat exchange is also an extremely important mechanism. What would we call heat movement in a non-gravity situation caused by diffusion of a gas? User:rjstott

[edit] Equation with integral

In the equation that has the integral with apparently A_s as the lower limit, the subscript s for A_s does not show well. The s looks likes it's part of the integrand instead of the lower limit. I'm not sure at this time how to fix this problem. H Padleckas 11:06, 9 Jul 2004 (UTC)

[edit] Thermal convection, Rayleigh-Benard convection, Maringoni convection, Solutal convection

Thermal convection redirects here, but isn't mentioned in the article. Is it superfluous (is all convection thermal)? Also, Weisstein's physics encyclopedia says that thermal convection is also called Rayleigh-Benard convection. This web page says that, "the stripe or roll state formed in bouyancy driven convection is today referred to as Rayleigh-Benard convection. Surface tension induced convection is known as Maringoni convection." -- Kjkolb 00:50, 28 November 2005 (UTC)

I also found something called solutal convection, but I've been unable to find out its definition. -- Kjkolb 02:59, 28 November 2005 (UTC)

[edit] fluid

Adding after the use of 'fluid' in the first paragraph "which can be a liquid, gas, or plasma" would help readers who see fluid and think that it means liquid, which I am guessing is not an uncommon mistake.

[edit] convection and HVAC

For my part, I was hoping to find here a discussion relating to HVAC and ovens and how convection heaters and convection ovens differ from the conventional kinds--or whether the term in those cases is misapplied in some sense.

Thanks.

[edit] Pattern Forming

The pattern forming section is very confusing (even to someone who understands convection already). It should probably be removed or at least moved to its own article. Anonymous6494 06:13, 4 December 2006 (UTC)
