Figure 1: Left: relative permeabilities of the gas and liquid phase k r α , α ∈ P function of the liquid saturation S l
Figure 1 exhibits the gas saturation, and the extended gas and liquid pressures P e g , P e l at different times obtained with the mesh N = 559 and the PPF formulation.
Figure 2: Gas saturation, and extended gas and liquid pressures P e g , P e l at times t = 1 day, 1 month, 6 months, 1 year, 2 years, 4 years, and 10 years obtained with the mesh N = 559 and the PPF formulation.
Figure 4: Extended air molar fraction in the gas phase e c g a in the four cases (i) D l = D g = 0 m 2 .s −1 ; (ii) D l = 0 m 2 .s −1 , D g = 10 −7 m 2 .s −1 ; (iii) D l = 3 10 −9 m 2 .s −1 , D g = 10 −7 m 2 .s −1 ; (iv) D l = 3 10 −9 m 2 .s −1 , D g = 0 m

27 (2005), 914–936], we propose a relaxation scheme for the numerical simulation of one-dimensional two-phase multi-component flows governed by a drift-flux model, the main features

For a fixed temperature under a critical value, a coexistence line is obtained in the plane of neutron and proton chemical potentials.. Along this line, the grand potential presents

data coherence occurs when data are replicated on different cache memories of cores, due to concurrent read and write operations. Versions of data may differ between cores and with

As it results from the work function measurements, there is no evidence of segre- gation in yttria doped Zr02 which might lead to changes in the structure of the

The following abbreviations for the characters are used throughout the text: DAA – dorsal anchor to- tal length; DAB – dorsal anchor main part length; DAC – dorsal anchor outer

Among the 14 biological traits for which the species of the system were assigned with values, we expect the trait of tolerance to tidal emersion and low salinity levels (T5) along
