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
This paper investigates the heat transfer characteristics of oscillating flow in active magnetocaloric regenerator (AMR) by numerical simulation. We show that the operating frequency plays an important role to the heat transfer coefficient of the regenerator other than the Reynolds number and the Prandtl number. Moreover, to reveal the mechanism of the frequency correlated heat transfer characteristics, a modified synergy number Fci is proposed based on the field synergy principle. To quantitatively describe the influence of operating frequency, the oscillating Reynolds number is introduced. This paper compares the heat transfer coefficient calculated by three different methods: CFD simulation, correlations with the oscillating Reynolds number and correlations with the conventional Reynolds number. Based on the results of comparison, this paper qualitatively presents a frequency correlated heat transfer correlation for different operating frequency. In addition, a perforated parallel plate matrix regenerator is proposed to improve the heat transfer performance of the AMR.
