transfer of heat
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 …
2Heat 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… …
3Heat 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… …
4heat transfer — heat transfer, the flow of heat from warmer bodies to colder bodies; the transfer of heat between solids, liquids, or gases, by conduction, convection, or radiation …
5heat exchange — heat exchange, = heat transfer. (Cf. ↑heat transfer) …
6heat convection — transfer of heat from one place to another …
7Heat exchanger — An interchangeable plate heat exchanger Tubular heat exchan …
8Heat 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… …
9Heat — 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… …
10heat — heatable, adj. heatful, adj. heatless, adj. heatlike, adj. /heet/, n. 1. the state of a body perceived as having or generating a relatively high degree of warmth. 2. the condition or quality of being hot: the heat of an oven. 3. the degree of… …
