  2. Wet gas - Wikipedia

    en.wikipedia.org/wiki/Wet_gas

    Void fraction is the ratio of the flow area occupied by the gas to the total flow area. Lockhart–Martinelli parameter. [5] Gas is compressible and the density changes significantly with changes in pressure. Liquids, on the other hand, are considered to be incompressible and so their density does not tend to change with a change in pressure.

  3. Porosity - Wikipedia

    en.wikipedia.org/wiki/Porosity

    Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell ...

  4. Permeability of soils - Wikipedia

    en.wikipedia.org/wiki/Permeability_of_soils

    The coefficient of permeability varies with the void ratio as e/sup>/(1+e). For a given soil, the greater the void ratio, the higher the value of the coefficient of permeability. Here 'e' is the void ratio. Based on other concepts it has been established that the permeability of a soil varies as e 2 or e 3 /(1+e). Whatever may be the exact ...

    The concept of permeability is of importance in determining the flow characteristics of hydrocarbons in oil and gas reservoirs, [4] and of groundwater in aquifers. [5]For a rock to be considered as an exploitable hydrocarbon reservoir without stimulation, its permeability must be greater than approximately 100 md (depending on the nature of the hydrocarbon – gas reservoirs with lower ...

  6. Cavitation - Wikipedia

    en.wikipedia.org/wiki/Cavitation

    There are different flow patterns detected as a cavitation flow progresses: inception, developed flow, supercavitation, and choked flow. Inception is the first moment that the second phase (gas phase) appears in the system. This is the weakest cavitating flow captured in a system corresponding to the highest cavitation number. When the cavities ...
