Metric Options: CountsSelecting 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.

Conference Paper Description
In this work, a detailed numerical simulation of the gas flow through a heated open cell foam material was carried out. For this, several models of porous media were created with several values of porosity and the same surface area. Numerical studies were carried out in the ANSYS Fluent software package. The calculations used the SST turbulence model. The validity of the use of this model was confirmed based on direct numerical calculations performed on several models with a detailed breakdown of the grid (60 million cells). Good agreement was found between the results of calculations using DNS obtained on a detailed grid and a relatively rough network with the SST turbulence model. While maintaining the surface area of the material, porosity only affects the pressure drop while keeping the heat transfer characteristics. Creating heat exchangers from porous structures while maintaining thermal characteristics and low hydrodynamic resistance will be useful when using forced convection.
