摘要
给出了用于发动机多场耦合数值仿真的统一的数学模型,这一模型由于采用了广义控制体系,在用来求解非定常气、热、弹耦合的变域差分问题时很方便. 讨论了统一的数学模型在不同场的演化,分析了多场耦合的4种类型及发动机多种层次的物理模型与数学模型.
In the paper a mathematical model of three-dimensional multi-field couple in gas turbine engine is developed to establish numerical simulation test-bed. Adopting generalized control system, this model could be used to solve coupling question of unsteady aerodynamics, heat transfer and elasticity in varying region. On the other hand, evolation of the model according to different fields is discussed, including four types of couplings as well as physical and mathematical models of different levels.
