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
A new and simple method is established to examine the radial porosity profile of mono-sized spheres in packed bed cylinders based on the sphere center coordinates. The method is derived from geometrical and analytical techniques and uses arc lengths to calculate the radial porosity profile at any given axial position, a given interval axial position, or the total axial position, thus evaluating the local, interval, or axially averaged radial porosity profile, respectively. The new method and analytical functions are simple and straightforward and provide an accurate representation of the radial porosity profile given the sphere center coordinates. The simple method is used to calculate the radial porosity profile for the fixed packing of identical spheres in cylindrical containers with D / d ≥ 1.0. The evaluated results for the radial porosity profile are benchmarked with existing analytical equations and available experimental and numerical data, respectively, for mono-sized spheres in cylindrical containers. A concise FORTRAN program for the new arc length-based technique is presented for this simple method for calculating radial porosity profiles.
