Abstract :
High temperature pneumatic duct system is one of the most significant components of Air Management System (AMS). They act as transfer pipes for air flow at high temperature and pressure. The thermal analysis of the ducts is a key issue for the design of the AMS since the ducts have a great influence on its environment and the neighboring devices in the cabin. Based on the analysis of structure dimensions, position of the ducts in the cabin, materials properties, and operating conditions of the high temperature pneumatic duct system, the engineering method and finite volume method are used to investigate thermal and flow behaviors of the ducts in this paper. Main attention is focused on the factors such as duct arrangement and the characteristics of the heat insulation layer that influence the flow pattern and thermal performances. This work could be helpful for the optimization design of China´s civil-aircraft ducting system.
