permeability

[‚pər·mē·ə′bil·əd·ē]
(electromagnetism)
A factor, characteristic of a material, that is proportional to the magnetic induction produced in a material divided by the magnetic field strength; it is a tensor when these quantities are not parallel. Also known as magnetic permeability.
(fluid mechanics)
The ability of a membrane or other material to permit a substance to pass through it.
Quantitatively, the amount of substance which passes through the material under given conditions.
(geology)
The capacity of a porous rock, soil, or sediment for transmitting a fluid without damage to the structure of the medium. Also known as conductivity; perviousness.
(naval architecture)
The percentage of a given space in a ship that can be occupied by water.

permeability

1. The property of a porous material which permits the passage of water vapor through it. Also See permeance.
2. The property of soil, rock, or mantle which permits water to flow through it.

Because the proportion of N2 in air accounts for 79.8% and it is very convenient to obtain compressed air under the mine, the air injection is selected to enhance the permeability. Therefore, the numerical simulation process uses air as the simulation condition, and the compressed air in the compressed air system is taken as the gas source to conduct the field gas injection permeability enhancement test.
