Numerical simulation of two-dimension unsteady flow field in aircraft pneumatic system
2016
The two dimensions model of aircraft pneumatic system with constant volume tank is established, the model includes constant volume tank, orifice and pipe. The heat transfer among the air inside the pneumatic system, pneumatic components and air outside the pneumatic system is involved in the simulation. The two dimensions unsteady flow field in charging and discharging tank is calculated. After charging and discharging, the temperature of components in the system is different, the lowest temperature is the orifice's surface temperature. With the method displaced in this article, the two dimensions flow field in pneumatic system can be obtained.
