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 icing phenomenon of rotor presents strong couplings among multi-physical fields, which is highly affected by the instantaneous flowfield, physical environment and flight conditions, leading to potential distinct structural properties. To address this issue, the CLORNS-ICE algorithm is introduced to simulate the icing phenomenon of rotor, and whereby the features of ice profile are extracted to obtain the sectional coefficients of iced blade. The structural model of rotor is developed to consider the non-classical nonlinearities due to ice accretion by virtue of finite element method. The influence mechanisms of environmental factors, inflow state and structural parameters on the structural characteristics of rotor are revealed by means of parametric analyses, in which the modal properties of iced blade are analyzed through comparative analyses. The developed method also provides guidance for the comprehensive dynamic analysis of rotating blade during ice accretion.
