In the context of heat and mass transfer, the term " convection " is used to refer to the sum of advective and diffusive transfer.

Note that in common use the term convection may refer loosely to heat transfer by convection, as opposed to mass transfer by convection, or the convection process in general.

The convection term is often written as

The convection term may, by a vector calculus identity, be expressed without a tensor derivative:

The term radiator in this context is misleading since most heat transfer from the heat exchanger is by convection, not radiation.

A third term, thermal transmittance, incorporates the thermal conductance of a structure along with heat transfer due to convection and radiation.

The air tends to rise in an updraft through the process of convection ( hence the term convective precipitation ).

Despite the name, radiators generally transfer the bulk of their heat via convection, not by thermal radiation, though the term " convector " is used more narrowly ; see radiation and convection, below.

One might expect the term " radiator " to apply to devices that transfer heat primarily by thermal radiation ( see: infrared heating ), while a device which relied primarily on natural or forced convection would be called a " convector ".

In practice, the term " radiator " refers to any of a number of devices in which a liquid circulates through exposed pipes ( often with fins or other means of increasing surface area ), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.

This can change due to the unsteadiness in the flow captured by ( the unsteady term ) or due to the motion of the fluid particle as it moves from one point to another, ( the convection term ).

Forced convection is a term used when the streams and currents in the fluid are induced by external means — such as fans, stirrers, and pumps — creating an artificially induced convection current.

It was in this work that he coined the term " convection " to describe a type of energy transfer.

Crossover is the term used to describe the tube that connects from the convection section outlet to the radiant section inlet.

In addition to the wide range of length and time scales and the associated computational cost, the governing equations of fluid dynamics contain a non-linear convection term and a non-linear and non-local pressure gradient term.

This is the convection or the advection term.

`` I may possibly be a greater risk than is the normal person of my age '', the President had said on February 29th of the election year, ignoring the fact that no one of his age had ever lived out another term.

For the near term, however, it must be realized that the industrial and commercial market is somewhat more sensitive to general business conditions than is the military market, and for this reason I would expect that any gain in 1961 may be somewhat smaller than those of recent years ; ;

The term altruism may also refer to an ethical doctrine that claims that individuals are morally obliged to benefit others.

Abnormal and pathological anxiety or fear may itself be a medical condition falling under the blanket term " anxiety disorder ".

The term may be common to Italo-Celtic, because the Celtic languages have terms for high mountains derived from alp.

The term analog signal usually refers to electrical signals ; however, mechanical, pneumatic, hydraulic, and other systems may also convey analog signals.

" Capitalism ," as anarcho-capitalists employ the term, is not to be confused with state monopoly capitalism, crony capitalism, corporatism, or contemporary mixed economies, wherein market incentives and disincentives may be altered by state action.

In statistics, the term analysis may refer to any method used

The term may also refer to the physical region where the electron can be calculated to be, as defined by the particular mathematical form of the orbital.

Most often, the term describes those who create within a context of the fine arts or ' high culture ', activities such as drawing, painting, sculpture, acting, dancing, writing, filmmaking, photography, and music — people who use imagination, talent, or skill to create works that may be judged to have an aesthetic value.

The term may be also used loosely or metaphorically to denote highly skilled people in any non -" art " activities, as well — law, medicine, mechanics, or mathematics, for example.

English, French, German, Italian, Japanese, Hebrew, Arabic, Portuguese, and Russian speakers may use the term American to refer to either inhabitants of the Americas or to U. S. nationals.

They generally have other terms specific to U. S. nationals, such as German US-Amerikaner, French étatsunien, Japanese 米国人 beikokujin, Arabic أمريكاني amriikaanii ( as opposed to the more-common أمريكي amriikii ), and Italian statunitense, but these may be less common than the term American.

Latin Americans also may employ the term norteamericano ( North American ), which conflates the United States, Canada and Mexico.

Its coastal acquisition may have been one reason yellow amber came to be designated by the same term as ambergris.

The second suggestion is " vine ", which is reached through * Ambilō, which may be related to the Greek term ámpelos, itself meaning " vine, liana ".

Although the term aeon may be used in reference to a period of a billion years ( especially in geology, cosmology or astronomy ), its more common usage is for any long, indefinite, period.

" " Giving Directions " is the term for thinking and projecting an anatomically ideal map of how one's body may be used effortlessly.

However, some immigrants from African, Caribbean, Central American and South American nations, and their descendants, may be identified or self-identify with the term.

The Dictionary of Politics: Selected American and Foreign Political and Legal Terms defines the term Alford plea as: " A plea under which a defendant may choose to plead guilty, not because of an admission to the crime, but because the prosecutor has sufficient evidence to place a charge and to obtain conviction in court.

The term may also apply to works of fiction purporting to be autobiographies of real characters, e. g., Robert Nye's Memoirs of Lord Byron.

As with those who engage other activities such as singing or running, the term may apply broadly to anyone who engages in it even briefly, or be more narrowly limited to those for whom it is a vocation, habit or characteristic practice.
