 Physical properties of the specimens under investigation, where L and w are the length and width of the aperture field of the specimen, respectively, \(b_{\text{mean}}\) and \(\sigma\) are the mean and the standard deviation of the aperture distributions, respectively, \({L}_{\text{c}_\text{x}}\) is the normalized correlation length in the flow direction, and \({L}_{\text{c}_\text{y}}\) is the normalized correlation length in the direction perpendicular to the flow
