r,L] are the experimental relative permeability
coefficient of the blends and the relative permeability
coefficient of the blends calculated by Eqs.
In the same conditions, the water saturation drops quickly if the gas saturation is high, similarly, if the gas relative permeability
increases the water relative permeability
decreases, the production of CBM improves, the gas pressure fall sharply to a stationary value which means extraction turns into the state of fast gas-generating.
As mentioned before, the relative permeability
of mild steel is non-linear.
The alternative relative permeability
function for EDZ and clay rocks (S2) does not change gaseous fluxes, because free gas movement is dominating through the interfaces.
While the relative permeability
in the fracture is evaluated using the following equations:
In this figure, region 1 is free space; region 2 is a coated RAM layer with the relative permittivity [epsilon] and the relative permeability
sp]=0,5 mm, the thickness of the magnet poles e=5 mm, the distance between the upper and lower parts of the electromagnet core h=25 mm, the terminal width b=150 mm, and the relative permeability
of the magnetic core [mu]rs=1000.
According to Honarpour et al (2008), rock characterization involves quantification of porosity, permeability, capillary pressure, and relative permeability
associated with various recovery processes.
or]) is the relative permeability
to water at the residual oil saturation, fraction; [K.
Permeability was computed using a The relative permeability
(K/Ko) measured as a function of electrolyte concentration, following leaching of the soil columns with solutions of SAR 5, 15, and 30 are shown in Figure 2.
0] is permeability of free space, pr is conductor's relative permeability
and f is sine-wave frequency.
As in metamaterial we can change the value of relative permittivity as well as relative permeability
at a particular frequency by suitable inclusions so we can achieve maximum radiation intensity by using metamaterial.
