Heat flux — or thermal flux is a flow of energy per unit of area per unit of time. In SI units, it is measured in [W·m 2] . It has both a direction and a magnitude so it is a vectorial quantity. To define the heat flux at a certain point in space, one takes… … Wikipedia
Critical heat flux — describes the thermal limit of a phenomenon where a phase change occurs during heating (such as bubbles forming on a metal surface used to heat water), which suddenly decreases the efficiency of heat transfer, thus causing localised overheating… … Wikipedia
Heat flux sensor — A heat flux sensor is a commonly used name for a transducer generating a signal that is proportional to the local heat flux. This heat flux can have different origins; in principle convective , radiative as well as conductive heat can be measured … Wikipedia
Latent heat flux — is the flux of heat from the Earth s surface to the atmosphere that is associated with evaporation of water at the surface and subsequent condensation of water vapor in the troposphere. It is an important component of Earth s surface energy… … Wikipedia
Sensible heat flux — is a term that is used for the flux of energy per square metre (Js 1m 2) in heating a surface without evaporating a liquid from it.ee AlsoLatent heat fluxExternal Links* http://www.uwsp.edu/geo/faculty/ritter/geog101/textbook/energy/energy… … Wikipedia
Heat 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 … Wikipedia
Heat conduction — or thermal conduction is the spontaneous transfer of thermal energy through matter, from a region of higher temperature to a region of lower temperature, and acts to equalize temperature differences. It is also described as heat energy… … Wikipedia
Flux footprint — (aka atmospheric flux footprint, footprint) is an upwind area where the atmospheric flux measured by an instrument is generated. Specifically, the term flux footprint describes an upwind area “seen” by the instruments measuring vertical turbulent … Wikipedia
Flux — This article is about the concept of flux in science and mathematics. For other uses of the word, see Flux (disambiguation). In the various subfields of physics, there exist two common usages of the term flux, both with rigorous mathematical… … Wikipedia
Heat — In physics, heat, symbolized by Q , is energy transferred from one body or system to another due to a difference in temperature. [cite book|author= Daintith, John |title=Oxford Dictionary of Physics|publisher=Oxford University… … Wikipedia
Heat transfer coefficient — The heat transfer coefficient, in thermodynamics and in mechanical and chemical engineering, is used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid::Delta Q=h cdot A cdot Delta T cdot Delta… … Wikipedia
