  2. Sublimation (phase transition) - Wikipedia

    en.wikipedia.org/wiki/Sublimation_(phase_transition)

    In order to transfer the image from the paper to the substrate, it requires a heat press process that is a combination of time, temperature and pressure. The heat press applies this special combination, which can change depending on the substrate, to “transfer” the sublimation dyes at the molecular level into the substrate.

  3. Snowmelt - Wikipedia

    en.wikipedia.org/wiki/Snowmelt

    Generally the net longwave radiation term is negative, meaning a net loss of energy from the snowpack. Latent temperature flux is the energy removed from or delivered to the snowpack which accompanies the mass transfers of evaporation, sublimation, or condensation. Sensible heat flux is the heat flux due to convection between the air and snowpack.

  4. Stefan problem - Wikipedia

    en.wikipedia.org/wiki/Stefan_problem

    The classical Stefan problem aims to describe the evolution of the boundary between two phases of a material undergoing a phase change, for example the melting of a solid, such as ice to water. This is accomplished by solving heat equations in both regions, subject to given boundary and initial conditions. At the interface between the phases ...

  5. Latent heat - Wikipedia

    en.wikipedia.org/wiki/Latent_heat

    If the vapor then condenses to a liquid on a surface, then the vapor's latent energy absorbed during evaporation is released as the liquid's sensible heat onto the surface. The large value of the enthalpy of condensation of water vapor is the reason that steam is a far more effective heating medium than boiling water, and is more hazardous.

  6. Ablation zone - Wikipedia

    en.wikipedia.org/wiki/Ablation_zone

    Ablation zone or ablation area refers to the low-altitude area of a glacier or ice sheet below firn with a net loss in ice mass. This loss can result from melting, sublimation, evaporation, ice calving, aeolian processes like blowing snow, avalanche, and any other ablation.

  7. Heat transfer - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer

    Phase change examples are the melting of ice or the boiling of water. The Mason equation explains the growth of a water droplet based on the effects of heat transport on evaporation and condensation. Phase transitions involve the four fundamental states of matter: Solid – Deposition, freezing, and solid-to-solid transformation.

  8. Dye-sublimation printing - Wikipedia

    en.wikipedia.org/wiki/Dye-sublimation_printing

    The printed transfer sheet is then pressed with the substrate with heat, transferring the dye to the substrate, such as plastic or fabric, via sublimation. [2] [1] Thus, this process is indirect, since the final substrate does not pass through the printer, and the sublimation step occurs separately. The term direct dye sublimation is sometimes ...

  9. Ablation - Wikipedia

    en.wikipedia.org/wiki/Ablation

    Ablation refers to the melting of snow or ice that runs off the glacier, evaporation, sublimation, calving, or erosive removal of snow by wind. Air temperature is typically the dominant control of ablation, with precipitation exercising secondary control.
