Calculation and analysis for bleed air anti-icing system of an aircraft wing was conducted
Influences of droplet diameter on impinging limits and Mach number on heat transfer coefficient were analyzed.Evaluation of the system's effectiveness at different flight height was conducted.The results showed that impinging limits increased with the droplet diameters increasing
heat transfer coefficient of the wing surface increased with the Mach number increasing
and dry temperature of anti-iced surface was higher than wet temperature under the same conditions.Results for several typical cross sections under different flight conditions indicated: for the given parameters
the system was effective at H=4 km and H=7 km
some wet temperature of anti-iced surface at H=7 km was lower than0 ℃.
