摘要

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 nonclassical 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. (C) nbsp;2022 Elsevier Masson SAS. All rights reserved.
