Research progress on airfoil icing characteristics and complex flowfield analysis
The theory of aircraft icing and its disaster mechanisms are crucial for preventing icing accidents and en-hancing flight performance.The research progress on the flow field characteristics under different icing conditions and special wing configurations are systematically summarized in this paper.It is pointed out that,the actual three-dimensional ice shapes are complex,have multiple structural features,and coupling mechanisms with separated flow and turbulence structures should be further studied.The aerodynamic performance analysis of special wings un-der supercooled large droplet conditions is the significant future research direction.Turbulence field analysis focuses on identifying instability characteristics of the icing wing flow field and multi-scale structural interaction mecha-nisms.Exploring the ice-flow coupling mechanism is of reference value for developing multi-factor,multi-parame-ter,and multi-scale icing prediction and computational models.
