Description
Summary:•A Double Compensation Chamber Loop Heat Pipe (DCCLHP) for the aircraft anti-icing system was developed.•Start-up performance, temperature oscillation and the operation characteristics were analyzed.•Different vapor/liquid distribution in the CCs with different heating power and the AOAs were observed.•The anti-icing performance was predicted. The objective of this research is to experimentally investigate the start-up and operating characteristics of the Double Compensation Chamber Loop Heat Pipe (DCCLHP) anti-icing system. The loop was made of stainless steel with nickel wick, and the working fluid was ethanol. Experiments were carried out with the heat loads from 10W to 180W. The angle of attack (AOA) is from −10° to 5°. It was found that: (1) in order to obtain a good anti-icing result, the DCCLHP anti-icing system should be turned on approximately ten minutes before the aircraft encountered cloud with super-cooled droplets; (2) temperature oscillations happened in the start-up process when the AOA is not 0°; (3) the positive AOA can increase the surface temperature, as a result of which the anti-icing effect could also be enhanced.
