In order to realize the design of gas-thermal anti-icing/deicing system by the technology of micro-channel based on the design of electromagnetic function structure gas-thermal anti-icing/deicing system based on micro-channel technology closely related to the fluid flow behavior and heat transfer characteristics of the internal/external flow field,a coupled flow field-heat transfer analysis method is proposed. The flow field and heat transfer characteristic of typical wing-front edge electromagnetic functional structures are simulated and analyzed by using gas-thermal hallow quartz fiber reinforced resin matrix composites as the micro-channel implementation method. The results show that with ambient temperature being at 15℃, the anti-icing/deicing scheme based on the technology of micro-channel is satisfied with the needs of anti-icing/deicing potential, and a theoretical support is provided for the subsequent optimization design of gas-thermal anti-icing/deicing scheme.
