  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. 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 ...

  4. Capillary flow porometry - Wikipedia

    en.wikipedia.org/wiki/Capillary_flow_porometry

    Therefore the pressure step/stability method is the most recommended one for research and development applications. Additionally, the pressure step/stability measuring principle allows measuring the true First Bubble Point (FBP), in opposition to the pressure scan method, which only permits calculation the FBP at the selected flow rates.

  5. Rayleigh–Plesset equation - Wikipedia

    en.wikipedia.org/wiki/Rayleigh–Plesset_equation

    The Rayleigh–Plesset equation is often applied to the study of cavitation bubbles, shown here forming behind a propeller.. In fluid mechanics, the Rayleigh–Plesset equation or Besant–Rayleigh–Plesset equation is a nonlinear ordinary differential equation which governs the dynamics of a spherical bubble in an infinite body of incompressible fluid.

  6. Critical point (thermodynamics) - Wikipedia

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

    The commonly known phases solid, liquid and vapor are separated by phase boundaries, i.e. pressure–temperature combinations where two phases can coexist. At the triple point, all three phases can coexist. However, the liquid–vapor boundary terminates in an endpoint at some critical temperature T c and critical pressure p c. This is the ...

  9. Kozeny–Carman equation - Wikipedia

    en.wikipedia.org/wiki/Kozeny–Carman_equation

    The equation was derived by Kozeny (1927) [1] and Carman (1937, 1956) [2] [3] [4] from a starting point of (a) modelling fluid flow in a packed bed as laminar fluid flow in a collection of curving passages/tubes crossing the packed bed and (b) Poiseuille's law describing laminar fluid flow in straight, circular section pipes.
