  2. Supercritical fluid - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid

    A supercritical fluid (SCF) is a substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist, but below the pressure required to compress it into a solid. [1]

  3. Critical point (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Critical_point...

    It is called supercritical fluid. The common textbook knowledge that all distinction between liquid and vapor disappears beyond the critical point has been challenged by Fisher and Widom , [ 8 ] who identified a p – T line that separates states with different asymptotic statistical properties ( Fisher–Widom line ).

  4. Non ideal compressible fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Non_ideal_compressible...

    With the term dense vapors, we indicate all fluids in the gaseous state characterized by thermodynamic conditions close to saturation and the critical point. [1] Supercritical fluids feature instead values of pressure and temperature larger than their critical values, [ 2 ] whereas two-phase flows are characterized by the simultaneous presence ...

  5. Transcritical cycle - Wikipedia

    en.wikipedia.org/wiki/Transcritical_cycle

    A transcritical cycle is a closed thermodynamic cycle where the working fluid goes through both subcritical and supercritical states. In particular, for power cycles the working fluid is kept in the liquid region during the compression phase and in vapour and/or supercritical conditions during the expansion phase.

  6. Supercritical flow - Wikipedia

    en.wikipedia.org/wiki/Supercritical_flow

    A supercritical flow is a flow whose velocity is larger than the wave velocity. [clarification needed] The analogous condition in gas dynamics is supersonic speed.According to the website Civil Engineering Terms, supercritical flow is defined as follows: The flow at which depth of the channel is less than critical depth, velocity of flow is greater than critical velocity and slope of the ...

  7. Supercritical carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Supercritical_carbon_dioxide

    More specifically, it behaves as a supercritical fluid above its critical temperature (304.128 K, 30.9780 °C, 87.7604 °F) [1] and critical pressure (7.3773 MPa, 72.808 atm, 1,070.0 psi, 73.773 bar), [1] expanding to fill its container like a gas but with a density like that of a liquid. Supercritical CO

  8. Supercritical adsorption - Wikipedia

    en.wikipedia.org/wiki/Supercritical_adsorption

    For example, “a fluid is considered to be ‘supercritical’ when its temperature and pressure exceed the temperature and pressure at the critical point”. In the studies of supercritical extraction, however, “supercritical fluid” is applied for a narrow temperature region of 1-1.2 T c {\displaystyle T_{c}} or T c {\displaystyle T_{c ...

  9. Supercritical - Wikipedia

    Supercritical carbon dioxide: Supercritical fluid chromatography, a form of liquid chromatography using supercritical carbon dioxide as the mobile phase; Supercritical water: Supercritical steam generator, a steam generator operating above the critical point of water, hence having no water–steam separation
