  • Thermal conductivity — In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It appears primarily in Fourier s Law for heat conduction.First, we define heat conduction by the formula::: H=frac{Delta Q}{Delta t}=k …   Wikipedia

  • thermal conductivity — noun 1. : capability of conducting heat 2. : the quantity of heat that passes in unit time through a unit area of plate whose thickness is unity when its opposite faces differ in temperature by one degree * * * Physics. the amount of heat per… …   Useful english dictionary

  • thermal conductivity — a material property that describes the rate at which heat flows within a body for a given temperature difference. Its units are W/m k …   Mechanics glossary

  • Thermal conduction — In heat transfer, conduction (or heat conduction) is a mode of transfer of energy within and between bodies of matter, due to a temperature gradient. Conduction means collisional and diffusive transfer of kinetic energy of particles of ponderable …   Wikipedia

  • thermal conduction — Transfer of heat energy resulting from differences in temperature between adjacent bodies or adjacent parts of a body. In the absence of a heat pump, the energy will flow from a region of higher temperature to a region of lower temperature. The… …   Universalium

  • Thermal insulation — The term thermal insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer.Heat energy can be transferred by conduction, convection, radiation or when undergoing a phase… …   Wikipedia

  • Thermal management of electronic devices and systems — Heat generated by electronic devices and circuitry must be dissipated to improve reliability and prevent premature failure. Techniques for heat dissipation can include heatsinks and fans for air cooling, and other forms of computer cooling such… …   Wikipedia

  • thermal diffusivity — a material property that describes the rate at which heat diffuses through a body. It is a function of the body s thermal conductivity and its specific heat. A high thermal conductivity will increase the body s thermal diffusivity, as heat will… …   Mechanics glossary

  • Thermal spraying — techniques are coating processes in which melted (or heated) materials are sprayed onto a surface. The feedstock (coating precursor) is heated by electrical (plasma or arc) or chemical means (combustion flame). Thermal spraying can provide thick… …   Wikipedia
