基于炯理论的飞机热利用系统分析及研究

旨在比较能量守恒法和炯平衡分析法在航空热利用设计领域的差异。建立了某一型号飞机发动机燃烧室和涡轮部件高温燃气热利用的模型，在模型基础上采用两种方法计算并比较其结果。分析结果表明，能量守恒法无法消除系统中多部件间的影响，炯分析法则避免了在一些不可能实现的状态下进行不必要计算，能够更好的在多部件系统的热利用优化方面发挥作用。因此，在飞机热能设计和优化分析过程中，炯分析法较之传统的能量守恒法能够更精确、更便捷的完成复杂系统的计算。

Analysis and Research of Aircraft Thermal Utilization System Based on Exergy Theory

The purpose of comparing two different methods in the field of aviation thermal utilization designing is the conservation of energy law analyses and the exergy balance analyses. A simply model of an aircraft engine＇s thermal utilization system was built. The two different methods were calculated based on the model. The results show that： the conservation of energy law analyses can not eliminate the influences between the muhi-part in the system. On the other hand,the exergy balance analyses can avoid some unnecessary calculates,could do better in lhe heat utilization optimization of a multi-part system. Therefore,in field of the aircraft thermal energy, design and in the optimized analysis process,the exergy balance analyses can be more precise and convenient to complete the complex system＇s calculation compared with the traditional conservation of energy law analyses.
