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
Loop heat pipes (LHPs) that passively operate, need no electric power, and can be flexibly arranged are promising in thermal control systems for both terrestrial and aerospace applications. Understanding the two-phase state in the porous media of the capillary evaporator induced by nucleate boiling is the key to enhancing the evaporator performance. This study visualizes the liquid–vapor (L–V) phase distribution on the contact surface between the cylindrical evaporator casing and the wick to investigate the L–V phase distribution and its relationship with the evaporator heat transfer coefficient. The observed results show the phase transition from a liquid-saturated to a two-phase state of the wick by nucleation boiling and the evolution of the L–V phase distribution with the changing heat load. In conclusion, the relationship between the heat-transfer coefficient and the length of the three-phase contact line within the heated casing, liquid, and vapor phases is discovered.
