“…This ''deviatoric behavior" was also found in the data by Tayebi et al (2000), as noted above, noting that the gas velocities were smaller and the gas density larger in the Tayebi data. To explain these anomalies in the droplet concentration profile, two hypotheses have been suggested by many authors: (1) Reynolds stress driven secondary flows in the pipe cross section generate sufficient cross sectional transport of droplets (Speziale, 1982, Williams et al, 1996, or (2) turbulence inhomogeneity modulates the distribution of droplets due to turbophoresis (Reeks, 1992).…”

“…Such modelling consists of an exponential concentration profile for each droplet size, by assuming constant diffusivity (homogeneous turbulence) throughout the flow cross section. The data examined in this work were those of Tayebi et al (2000), that covers the vertical diameter in a horizontal pipe.…”

“…[1][2][3][4][5][6] A great number of ways such as theoretical models, experimental methods and simulation approaches have been adopted to characterize the water-gas flow, among which some analytical solutions for the hydraulic properties of unsaturated hydraulic properties of fracture networks have been proposed. [7][8][9][10][11][12] Besides, the fractal dimension that can be used to quantify the geometric properties such as fracture length and aperture distributions of rock fractures has been widely accepted and incorporated into these models.…”

This study presented the analytical solutions for water-gas flow through three-dimensional (3D) fracture networks subjected to triaxial stresses. The relationship between fractal dimension for fracture aperture distribution subjected to triaxial stresses and that subjected to no stresses is established, and the analytical solutions for fractal dimensions for aperture distribution and the equivalent permeability of both fluid and gas phases were derived. The results show that the calculated relative permeability of water phase-saturation curves agree well with those reported in the literature, which indicates that the proposed solutions are validate. With the increment of normal stresses applied on the fracture surface, both the maximum aperture and § Corresponding author.

The fractal dimensions for fracture aperture distribution of water and gas phases with respect to saturation are axisymmetric along saturation = 0.5. With the increase in saturation, the fractal dimension for fracture aperture distribution of water phase increases significantly when the saturation is less than 0.1, and then gently when the saturation is continuously increased by up to 1.0. The normal stress increased by two orders of magnitude for a larger normal stress (i.e. increased from 10 −2 MPa to 10 MPa) corresponds to smaller variations in equivalent permeability of both water and gas phases for a smaller normal stress (i.e. increased from 10 −4 MPa to 10 −2 MPa).
