natural-convection heat transfer
1Heat transfer — is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase change …
2Natural convection — Bénard cells. Natural convection is a mechanism, or type of heat transport, in which the fluid motion is not generated by any external source (like a pump, fan, suction device, etc.) but only by density differences in the fluid occurring due to… …
3Convective heat transfer — See also: Heat transfer and convection This figure shows a calculation for thermal convection. Colors closer to red are hot areas and colors closer to blue are cold areas. In this figure, a hot, less dense lower boundary layer sends plumes… …
4heat transfer — ▪ physics any or all of several kinds of phenomena, considered as mechanisms, that convey energy and entropy from one location to another. The specific mechanisms are usually referred to as convection, thermal radiation (qq.v.), and… …
5Convection — This figure shows a calculation for thermal convection in the Earth s mantle. Colors closer to red are hot areas and colors closer to blue are cold areas. A hot, less dense lower boundary layer sends plumes of hot material upwards, and likewise,… …
6Convection–diffusion equation — The convection–diffusion equation is a parabolic partial differential equation combining the diffusion equation and the advection equation, which describes physical phenomena where particles or energy (or other physical quantities) are… …
7Convection oven — Although the word convection is usually used to describe the natural circulation of gas or liquid caused by temperature differences, the convection in convection oven has a more general definition: the transfer of heat via movement of gas or… …
8convection — convectional, adj. /keuhn vek sheuhn/, n. 1. Physics. the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. 2. Meteorol. the vertical transport of atmospheric properties, esp. upward (distinguished from… …
9Natural environment — This article is about the environment. For other uses, see Environment (disambiguation). See also: Nature Land management policies have been developed to preserve the natural characteristics of Hopetoun Falls, Australia while allowing ample… …
10Ground-coupled heat exchanger — Earth cooling tubes or earth warming tubes (also known as ground coupled heat exchangers) utilize the earth s near constant subterranean temperature to warm or cool air for residential, agricultural or industrial uses. They are often a viable and …
