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 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
forced convection — noun The convection (carriage) of contents of a fluid, such as mass or (especially) heat, by means of currents induced in the fluid by a force which is not dependent on density changes in the fluid induced by heat. Transfer of heat from the… … Wiktionary
Convective 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… … Wikipedia
forced convection — [1] Transfer of heat resulting from forced movement of liquid or gas by means of a fan or pump. [2] Movement of fluid by mechanical force such as fans or pumps … Dictionary of automotive terms
Convection — 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,… … Wikipedia
Heat sink — A heat sink (or heatsink) is an environment or object that absorbs and dissipates heat from another object using thermal contact (either direct or radiant). Heat sinks are used in a wide range of applications wherever efficient heat dissipation… … 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 pipe — A heat pipe is a heat transfer mechanism that can transport large quantities of heat with a very small difference in temperature between the hotter and colder interfaces. Inside a heat pipe, at the hot interface a fluid turns to vapour and the… … Wikipedia
convection — 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… … Universalium
Natural 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… … Wikipedia
