coefficient of heat conduction
91Thermoélectrique — Thermoélectricité Découvert puis compris au cours du XIXe siècle grâce aux travaux de Seebeck, Peltier ou encore Lord Kelvin, l effet thermoélectrique est un phénomène physique présent dans certains matériaux : il y lie le flux de… …
92ice in lakes and rivers — Introduction a sheet or stretch of ice forming on the surface of lakes and rivers when the temperature drops below freezing (0° C [32° F]). The nature of the ice formations may be as simple as a floating layer that gradually thickens, or it …
93Differential equation — Not to be confused with Difference equation. Visualization of heat transfer in a pump casing, created by solving the heat equation. Heat is being generated internally in the casing and being cooled at the boundary, providing a steady state… …
94Stirling engine — Alpha type Stirling engine. There are two cylinders. The expansion cylinder (red) is maintained at a high temperature while the compression cylinder (blue) is cooled. The passage between the two cylinders contains the regenerator …
95welding — Technique for joining metallic parts, usually through the application of heat. Discovered in the 1st millennium AD during attempts to manipulate iron into useful shapes, the technique produced a strong, tough blade. Welding traditionally involved …
96Ocean thermal energy conversion — Temperature differences between the surface and 1000m depth in the oceans Ocean Thermal Energy Conversion (OTEC) uses the difference between cooler deep and warmer shallow or surface ocean waters to run a heat engine and produce useful work,… …
97Falling film evaporator — A falling film evaporator is a industrial device to concentrate solutions, especially with heat sensitive components. The evaporator is a special type of heat exchanger, Evaporator. In general evaporation takes place inside tubes. But there are… …
98electromagnetic radiation — Physics. radiation consisting of electromagnetic waves, including radio waves, infrared, visible light, ultraviolet, x rays, and gamma rays. [1950 55] * * * Energy propagated through free space or through a material medium in the form of… …
99Eddy current — This article is about the electrical phenomenon. For the Ted McKeever comic, see Eddy Current (comics). Electromagnetism …
100Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… …
