- Abstract:
- Taking one liquid rocket engine as example, the characteristic method is adopted to establish a one-dimension mathematical model of the propellant feeding system on the basis of water-hammer pressure theory. The numerical simulation of water-hammer pressure as the engine is shut down. The effect of the manometry conduit on the water-hammer process is computed and analyzed with the example.
