Numerical simulation and analysis on anti-icing effect of an anti-icing structure of temperature sensor is carried out

based on STAR-CCM + 11. 06

a computational fluid dynamics（ CFD） computation and simulation software. Flow field around anti-icing structure

movement mode of overcooled water droplets

the over cooled water droplets collection of anti-icing structure surface and ice layer growth and shape of icing layer. The result shows that the anti-icing structure can get good effect when the mach number Ma is above 0. 1

and the effect will get worse for lower mach number; sustainable growth will cause pipe freezing

anti-icing structure not having the ability of self-cleaning.
