Calado and Advani [29] proposed an analytical model to predict the contribution of each fabric layer to the average
permeability. However, the model does not consider hybrid preforms with fiber types of different specific masses, fiber volume fractions (fabric porosity), and tortuosity effects.
where: D is
permeability damage rate; [K.sub.i] is the
permeability at the first pressure [P.sub.i] in the experiment; K is the
permeability at a certain pressure P in the experiment.
Figure 2 shows that the changes of sandstone
permeability with confining pressure at different heating temperatures.
The mechanism of gas injection technology to improve
permeability is mainly based on the different adsorption capacities of C[H.sub.4], C[O.sub.2], [N.sub.2], and other gases.
The
permeability tests were carried out in a room with the temperature of 21 [+ or -] 1[degrees]C, using Darcy's Law to determine the
permeability coefficient from daily readings (Head, 1982).

permeability increase.
By applying Darcy's and Poiseuille's Laws, a relationship between porosity and
permeability can be derived as the following equation:
Intense, endurance exercise, such as running in the heat, is associated with greater gut
permeability. Try gardening, nature walks, or pilates instead.
