Influence of Diversion Tunnels on Insulation Design of the High Temperature Pneumatic Duct

Abstract:

Based on the research of air-duct system in ARJ21-700, insulation design is studied in this paper. Considering its specific characteristics, CFD method based on FLUENT is taken to its thermodynamic calculation. The result shows that diversion tunnels along the pipeline have remarkable effects on the skin temperature distribution of the heat-insulating layer, while differ with diversion tunnels’ amounts. These effects should be adopted into the engineering algorithm and these works would be helpful to the design and optimization of the air-duct system.
