  2. Maximum bubble pressure method - Wikipedia

    en.wikipedia.org/wiki/Maximum_bubble_pressure_method

    Figure 2: Change of pressure during bubble formation plotted as a function of added volume. Initially a bubble appears on the end of the capillary. As the size increases, the radius of curvature of the bubble decreases. At the point of the maximum bubble pressure, the bubble has a complete hemispherical shape whose radius is identical to the ...

  3. Random phase approximation - Wikipedia

    en.wikipedia.org/wiki/Random_phase_approximation

    Bubble diagrams, which result in the RPA when summed up. Solid lines stand for interacting or non-interacting Green's functions, dashed lines for two-particle interactions. The random phase approximation (RPA) is an approximation method in condensed matter physics and nuclear physics.

  4. Souders–Brown equation - Wikipedia

    en.wikipedia.org/wiki/Souders–Brown_equation

    The diameter of a vapor–liquid separator drum is dictated by the expected volumetric flow rate of vapor and liquid from the drum. The following sizing methodology is based on the assumption that those flow rates are known.

  5. Bubble point - Wikipedia

    en.wikipedia.org/wiki/Bubble_point

    In thermodynamics, the bubble point is the temperature (at a given pressure) where the first bubble of vapor is formed when heating a liquid consisting of two or more components. [ 1 ] [ 2 ] Given that vapor will probably have a different composition than the liquid, the bubble point (along with the dew point ) at different compositions are ...

  6. Marangoni effect - Wikipedia

    en.wikipedia.org/wiki/Marangoni_effect

    The effect of the Marangoni effect on heat transfer in the presence of gas bubbles on the heating surface (e.g., in subcooled nucleate boiling) has long been ignored, but it is currently a topic of ongoing research interest because of its potential fundamental importance to the understanding of heat transfer in boiling. [8]

  7. Feynman diagram - Wikipedia

    en.wikipedia.org/wiki/Feynman_diagram

    The vacuum bubbles are the same whatever the external lines, and give an overall multiplicative factor. The denominator is the sum over all vacuum bubbles, and dividing gets rid of the second factor. The vacuum bubbles then are only useful for determining Z itself, which from the definition of the path integral is equal to:

  9. Nanobubble - Wikipedia

    en.wikipedia.org/wiki/Nanobubble

    In 1994, a study by Phil Attard, John L. Parker, and Per M. Claesson further theorized about the existence of nano-sized bubbles, proposing that stable nanobubbles can form on the surface of both hydrophilic and hydrophobic surfaces depending on factors such as the level of saturation and surface tension.
