Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Experiments on the miscible displacement of a clear fluid by a dyed fluid of the same viscosity and density in a rectangular quasi-two-dimensional porous medium are presented. Equiconcentration dispersion fronts were identified using computer image processing. The fronts taken at three different concentrations are fractal curves with approximately the same box fractal dimension D1.45. In an alternative analysis the fronts were reduced to single valued functions and the dynamic scaling behavior investigated using a self-affine scaling formalism. The Hurst exponent H=0.55 and the dynamic exponent β=0.5, found by collapsing height difference correlation function data, are consistent with the results obtained through other analysis methods. The average concentration profile across the dispersion front was found to follow the classical solution of the diffusion-convection equation. The dependence of the width of the equiconcentration dispersion front σ on time yields dispersion coefficients Dσ over one order of magnitude less than the longitudinal dispersion coefficient D. © 1994 The American Physical Society.
