Simulation of a Short-cabin Anti-ice Chamber Flow and Heat Exchange of an Aero-engine
This study focuses on the thermal anti-icing of the engine nacelle inlet lip.A three-dimen-sional model was established to quantitatively analyze the effects of different bleed air velocities and tempera-tures on the flow and heat transfer within the anti-icing cavity.By conducting calculations,it was found that increasing the bleed air velocity from 10 m/s to 40 m/s resulted in a decrease in the minimum temperature on the anti-icing surface from 266.4 K to 286.2 K.Similarly,increasing the bleed air temperature from 100 ℃ to 130 ℃ raised the minimum temperature on the anti-icing surface from 286.2 K to 307.1 K.Therefore,effective anti-icing of the engine nacelle inlet lip can be achieved when the bleed air velocity is not lower than 15 m/s and the incoming flow temperature is not lower than 380 K.
