  2. Heat transfer coefficient - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer_coefficient

    Although convective heat transfer can be derived analytically through dimensional analysis, exact analysis of the boundary layer, approximate integral analysis of the boundary layer and analogies between energy and momentum transfer, these analytic approaches may not offer practical solutions to all problems when there are no mathematical models applicable.

  3. Heat transfer - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer

    Earth's longwave thermal radiation intensity, from clouds, atmosphere and surface.. Heat transfer is the energy exchanged between materials (solid/liquid/gas) as a result of a temperature difference.

  4. Condenser (heat transfer) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(heat_transfer)

    The earliest laboratory condenser, a "Gegenstromkühler" (counter-flow condenser), was invented in 1771 by the Swedish-German chemist Christian Weigel. [2]By the mid-19th century, German chemist Justus von Liebig would provide his own improvements on the preceding designs of Weigel and Johann Friedrich August Göttling, with the device becoming known as the Liebig condenser.

  5. Latent heat - Wikipedia

    en.wikipedia.org/wiki/Latent_heat

    Latent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process—usually a first-order phase transition, like melting or condensation.

    Otto cycle pressure–volume diagramThe idealized diagrams of a four-stroke Otto cycle Both diagrams: the intake (0-1 and colored green) stroke is performed by an isobaric expansion, followed by an adiabatic compression (1-2 and colored orange) stroke.

  7. Thermal-transfer printing - Wikipedia

    en.wikipedia.org/wiki/Thermal-transfer_printing

    Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.

  8. Bone conduction - Wikipedia

    en.wikipedia.org/wiki/Bone_conduction

    Bone conduction is one reason why a person's voice sounds different to them when it is recorded and played back. Because the skull conducts lower frequencies better than air, people perceive their own voices to be lower and fuller than others do, and a recording of one's own voice frequently sounds higher than one expects (see voice confrontation).
