| 摘 要： | 发动机空气系统可分别建立流体网络与热网络进行耦合计算。通过守恒方程进行迭代计算,并对参数进行修正,最终得到满意结果。提出一种流热耦合参数修正的思路,考虑了由于固体换热导致流体温度升高对密度及其他参数的影响。并以密度为标准,对其他参数进行修正,使计算结果更为准确。并通过编写空气系统部件集成仿真平台,实现局部快速三维仿真,得到流热网络计算所需的部分参数。

| Abstract: | The flow-thermal coupling calculation of aero engine air system includes fluid network and thermal network. By conservation equation, results will be get by iterative calculation, after each iteration, the parameters will be amendment. This paper presents an idea of the parameter modification of coupling calculation. Considering the effect of fluid temperature increasing resulted from solid heat transfer, density is set as the modifying standard. And some parameters for flow-thermal coupling calculation can be get by the local three-dimensional simulation. |
