Highlights
-
Thirty groups of aperture fields with different mean and standard deviation values were attained to investigated the effect of channeling flow on the permeability evaluation.
-
The ratio of permeability of elliptical models to that of equivalent rectangular models is proved to be controlled by the salience of channeling flow.
-
A corrected function was proposed to accurately calculate the permeability of elliptical fractures in the triaxial shear-flow experiments.
