| 摘 要： | 本文建立了流量残量方程组形式的燃气轮机性能的新数学模型，并提出了用Newton-Raphson和DFP－BFS优化组合解法来求解该模型。计算实践表明，该法不仅稳定性高、收敛速度快，而且求解精度高，可在任何工况下都得到较为满意的结果，在燃气轮机设计中有一定的实用价值。

| Abstract: | A new mathematical model composed of flow unbalance equations for gas turbine engine performance is established and the combined optidrization solution made up of Newton -Raphson and DPP -BFS methods is also presented. The computation practice shows that the solution of proposed method has not only good stability and rapid convergence,but also high accuracy. The computation results are satisfactory under various working conditions. |
