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.

Article Description
The initial velocity and mass flow rate of sulfur hexafluoride (SFg) released in the ionosphere are key factors for the release effects research. They are not involved in traditional simulation models. In order to realize high precision simulation, the flow field in the storage vessel during SF$ release is studied. According to the structural size of the SFe storage vessel, the geometric model is established, and the grid model uses structured grid and unstructured grid to discretize the computational area of the geometric model. Using the standard k-e model and SIMPLE algorithm in the professional software Fluent, the temperature, pressure, velocity of flow and mass flow rate in the storage vessel during SFe ionosphere release are simulated under different initial conditions, including initial temperature, pressure and filling mass. The flow field simulation results are taken as initial parameters in the three-dimensional refined model of SFg ionosphere release, and the refined effects of SFe ionosphere release are obtained.
