Editing Convection (section)

==Terminology==
Today, the word ''convection'' has different but related usages in different scientific or engineering contexts or applications.

In [[fluid mechanics]], ''convection'' has a broader sense: it refers to the motion of fluid driven by density (or other property) difference.<ref>{{cite book| title=Fundamentals of Fluid Mechanics| first= Bruce R. |last=Munson |isbn= 978-0-471-85526-2 |publisher = [[John Wiley & Sons]]| year= 1990 }}</ref><ref>{{cite book|last=Falkovich|first=G.|title=Fluid Mechanics, a short course for physicists|url=http://www.weizmann.ac.il/complex/falkovich/fluid-mechanics|publisher=Cambridge University Press|year=2011|isbn=978-1-107-00575-4|url-status=live|archive-url=https://web.archive.org/web/20120120034443/http://www.weizmann.ac.il/complex/falkovich/fluid-mechanics|archive-date=2012-01-20}}</ref>

In [[thermodynamics]], ''convection'' often refers to [[Convection (heat transfer)|heat transfer by convection]], where the prefixed variant Natural Convection is used to distinguish the fluid mechanics concept of Convection (covered in this article) from convective heat transfer.<ref>{{cite book|title=Thermodynamics:An Engineering Approach|first1= Yunus A. |last1=Çengel |first2= Michael A. |last2 = Boles |year= 2001 |isbn=978-0-07-121688-3 |publisher =[[McGraw-Hill Education]]}}</ref>

Some phenomena which result in an effect superficially similar to that of a convective cell may also be (inaccurately) referred to as a form of convection; for example, [[Marangoni effect|thermo-capillary convection]] and [[granular convection]].
