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 history modelling — is an exercise undertaken during basin modelling to evaluate the temperature history of stratigraphic layers in a sedimentary basin.The thermal history of a basin is usually calibrated using thermal indicator data, including vitrinite reflectance … Wikipedia
Thermal radiation — is electromagnetic radiation emitted from the surface of an object which is due to the object s temperature. Infrared radiation from a common household radiator or electric heater is an example of thermal radiation, as is the light emitted by a… … Wikipedia
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 diffusivity — In heat transfer analysis, thermal diffusivity (symbol: alpha,, but note that the symbols kappa, D, and k are all commonly used) is the ratio of thermal conductivity to volumetric heat capacity. It has SI of m²/s.:alpha = {k over { ho c pwhere: * … Wikipedia
Thermal effusivity — In Thermodynamics, the thermal effusivity of a material is defined as the square root of the product of the material s thermal conductivity and its volumetric heat capacity. [http://www.evitherm.org/default.asp?ID=277] :e = {(k ho c p)}^{1/2}Here … Wikipedia
Thermal management of high power LED — With the coming of energy saving era, high power light emitting diodes (LEDs) are promising to replace other technologies such as incandescent and fluorescent bulbs in signaling, solid state lighting, and vehicle headlight applications due to… … Wikipedia
Thermal copper pillar bump — The Thermal Copper Pillar Bump, also known as the thermal bump , is a thermoelectric device made from thin film thermoelectric material embedded in flip chip interconnects (in particular copper pillar solder bumps) for use in electronics and… … Wikipedia
Constitutive equation — Many defining equations are in the form of a constitutive equation, since parameters of a property or effect associated matter are characteristic to the substance in question. A large number of other defining equations not specifically… … Wikipedia
Classical and quantum conductivity — Classical and quantum mechanical views of conductivity have both described the movements of electrons in a metallic solid. The free electron gas that is present in metallic solids is the reason for an important property of all metals:… … Wikipedia
Heat equation — The heat equation is an important partial differential equation which describes the distribution of heat (or variation in temperature) in a given region over time. For a function of three spatial variables ( x , y , z ) and one time variable t ,… … Wikipedia
