Talk:Advection

message: I merged Advection with Advection Equation as both the articles are very small and there was a lot of overlap.  I think that one pages called advection with an advection equation heading would work fine.  If they get two big then separate them but at the moment I cannot really see the point as a description mathematically helps illustrate advection so they go hand-in-hand.

replies: text: I support the merge also, since nothing was lost, and I can't think of any reason for a separate section for advection math. Put it at the end, as here. But many of the variables in the math section are not defined, so somebody needs to work on it. SBHarris 19:01, 18 April 2007 (UTC)
thread_title: Merge

message: According to the article Convection, this term "is used to refer to the sum of advective and diffusive transfer". The description in the present article, however, seems to suggest that convection can mean the diffusive component only. Is there any support for this view?
Err, convection certainly includes buoyancy-driven flow so it is most definitely not just the diffusive component. djh 131.111.85.223 (talk) 09:42, 26 February 2010 (UTC)
replies: text: Convection is the sum of advection (bulk current transport) and diffusion, so it must have an advective component, or otherwise it would simply be called "diffusion." SBHarris 17:24, 26 February 2010 (UTC)
thread_title:  Advection vs. convection 

message: I just came here to find the meaning of advection, only to discover that it's not here! The page says a lot of things but assumes that you already know the meaning of the word. Somebody more expert than me should provide a simple but accurate definition. djh 131.111.85.223 (talk) 09:42, 26 February 2010 (UTC)
replies: text: The first sentence was okay, but the English was written so that it could be misunderstod. I've nailed it down, rearranged some material in the lede, and clearly differentiated it from convection, which is the sum of advection (bulk current transport of materials in fluids) and diffusion (transport which requires no currents).

thread_title:  Meaning of advection 

message: The clarity of the article would be much improved if U were defined and described when it is first introduced.--MuTau (talk) 18:48, 26 February 2011 (UTC)
thread_title:  Meaning of the vector field U 

message: A good scientist engineer can explain something to his peers; a great one can explain it to the average person.
The intro is a little to complicated and jargon laden; I would urge re writing along the lines of the advection vs convection (and eddy diffusion is in itself jargon).
Wiki has to satisfy people of wildly different skill sets; thus, the intros of articles like this need to be pitched at a level that is suitable for a very broad audience; technical detail, later on, is fine, but not in the intro.  —Preceding unsigned comment added by 108.7.14.40 (talk) 15:09, 26 April 2011 (UTC)

thread_title:  illustrations 

message: From the second last formula to the last formula, a factor 1/2 is introduced on the left side. This factor does not appear with the corresponding terms at the right side of the last formula.
This seems to be an error - can anybody confirm/disprove ?
The expression Nabla(uu) is not explained clear enough, and Nabla(uux),... does also not seem ultimately clear - a vector field multiplied by a scalar field ?

thread_title:  correctness and clarity of formulas 

message: Shouldn't there be a mention of volcanoes here? Advection is discussed on the Earth's internal heat budget page. -- Dough34 (talk) 18:51, 29 November 2019 (UTC)
thread_title:  Volcanoes? 

message: The diagram about the four fundamental modes of heat transfer does not mention evaporative cooling, which is misleading because there are more than four modes.—Anita5192 (talk) 13:37, 19 December 2023 (UTC)
