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
The present work aims at the optimum design and the optimum operating condition of a S-shaped diffuser by studying the effect of inlet velocity, turning angle and area ratio using Computational Fluid Dynamics. Fluent 17.1 software has been used for this simulation work. It is found that the static pressure recovery coefficient (C) increases and the total pressure loss coefficient (C) decreases as the inlet velocity increases. It is also found that cross-flow velocity becomes more prominent as turning angle increases and the magnitude of in-plane velocity increases with the increase in area ratio. It is further found that flow separation at the bottom wall increases with the increment in area ratio and decreases with the increase in turning angle. Finally, it is found that AR 4 is the optimum area ratio and 75°/75° is the optimum turning angle.
