Talk:Heat transfer coefficient

message: Shift this section to Thermal Conductivity. The resistance is by conduction and not by convection and should not be in Heat transfer coefficient. 220.255.2.144 (talk) 05:50, 14 May 2011 (UTC)
thread_title: Thermal resistance due to fouling deposits

message: As much as convective heat transfer is significant in nucleate boiling, this article not about boiling. It would be better placed in the article of Nucleate boiling. Venny85 (talk) 07:44, 9 May 2011 (UTC)
thread_title:  Shift Thom correlation to Nucleate boiling 

message: I removed some text from the article. It was a table of Prandtl number and thermal conductivity of air. Not really relevant to the article. My reasoning is this, Prandtl number has its own article, and equating thermal conductivity and heat transfer coefficient is just plain wrong. Especially for air.Djd sd (talk) 05:12, 30 January 2008 (UTC)

message: Is there any simple correlation for the heat transfer coefficient for the exterior of a pipe? (for instance when we have an insulated pipe exposed to the air)--190.160.181.235 (talk) 03:37, 11 September 2008 (UTC)
thread_title:  External Convection in Pipes 

message: This article contained a number of wrong statements, which I corrected, including the following:
"Heat transfer coefficient can be thought of as an inverse of thermal resistance."
Despite being full of weasel terms (why not just "is""? Why "an" inverse - are there more than one!?), it was also factually wrong, or at least it disagreed with the article Thermal conductivity, to which thermal resistance redirects. I replaced the link with "thermal insulance", even though I believe that the reader learns more about insulance here than on the other page. Nevertheless, the other page lists the related quantities in context, so that's of some use.  — Sebastian 03:02, 13 December 2008 (UTC)
thread_title:  Inverse 

message: Someone changed this section by switching the equations for adding heat coefficient in series vs. parallel. The section was correct before the change, so I changed it back. Check any college physics textbook. Heat transfer coefficients do not combine like electrical resistance.  —Preceding unsigned comment added by 192.12.184.2 (talk) 16:17, 24 February 2010 (UTC)
thread_title: Combining Heat Transfer Coefficients

message: For someone not already thoroughly familiar with the field this article is not very helpful. The introduction is OK but thereafter it goes downhill rapidly and the standard of technical writing is generally rather poor. Many terms are used in the equations without any explanation of what they are or the explanation occurs some distance after the terms are introduced. For example what is \mathrm{k}? What is {T}_{s}? What is {T}_{\infty }? What is a 'representative length'? What is \mathrm{Ra}? What is \mathrm{Re}? What is \mathrm{Pr}? What is \mathrm{Gr}? There is a figure with absolutely no explanation which is therefore useless.130.246.132.178 (talk) 10:34, 1 February 2012 (UTC)
thread_title:  This article is very poorly written 

message: The section about heat transfer coefficient of pipe wall looks incomplete. Is there a missing equation before line "where k is the effective thermal conductivity of the wall material and x is the wall thickness"?.

thread_title:  Heat transfer coefficient of pipe wall 

message: Since natural and forced convection correlations are concerned with the thermal convection coefficient, which is much more specific than the overall heat transfer coefficient, I suggest to move it to a page linked with thermal conductivity: there are simmetries and complementary aspects in Newton cooling law and Fourier law, and so on. This is not teaching anything about the overall heat transfer coefficient, so is very confusing in the actual structure and it could bring to misunderstanding if one try to compute the overall h.t.c. with one of these correlations --2.156.167.55 (talk) 17:18, 22 December 2013 (UTC)
thread_title:  Thermal convection correlation 

message: The section called Composition doesn't belong here.  It relates to practical examples of convection in pipes and walls.  It should be removed, or placed near the bottom of the article.  It also needs a more specific title.Parveson (talk) 13:24, 7 June 2019 (UTC)

message: Is the Inverse-square law applicable to the HTC? Was this topic ever discussed in relation to HTC? I'm curious. All the best. AXONOV (talk) ⚑ 16:08, 27 May 2022 (UTC)
