    Abstract
  • Based on fluid network method and mathematical models of components，the air system of engine compressor was simplified as a one-dimensional topological network composed of nodes and components.A program was developed to simulate this system for solving the flow control equations by the rotative mid-point mensuration combined with the Newton-Raphson method.The program was applied to simulation of the air system of a compressor test piece.The sensitivity analysis on the parameters of the air system of the test piece was carried out，and the main factors affecting the function of the air system were discussed.Results showed that the convergence speed and convergence region of Newton method can be increased by using the parametric differential method to solve the homotopy equation；in the compressor test piece，the flow path can be effectively separated by using the unloading chamber structure and the labyrinth with strong sealing ability，contributing to achieving the control objectives respectively.
