摘要
Abstract
To accurately simulate the aircraft electrothermal de-icing process,the coupling and synergistic effects among multiple physical fields must be considered.In this study,a multi-step icing numerical model and a multiphysics-coupled de-icing model were established,in which the dynamic interactions among the flow field,temperature field,stress field,and ice melting phase change were fully considered.The stress distribution characteristics at the ice-skin interface and within the two-dimensional accreted ice under chordwise local heating conditions during the de-icing process were analyzed,and the critical local heating range was determined based on multiphysics-coupled simulations.Furthermore,the mechanical responses of the ice under different flight velocities,altitudes,and liquid water contents were investigated.The results show that thermo-mechanical coupling induces significant stress responses in the ice,and the melting phase change further promotes stress evolution.A critical local heating range(with a heating coverage of 90%-95%)is identified.Under this condition,the shear stress exceeds the shear strength over more than 90%of the ice-skin interface,while the minimum principal stress exceeds the compressive strength over more than 99%of the ice near the ice-skin interface.These findings provide numerical support for analyzing the mechanical behavior of ice during aircraft electrothermal de-icing processes.关键词
