摘要:

引入内循环结构是提升飞机燃油热管理系统热沉利用效率的关键途径,但内循环会带来复杂的动力学特性,系统响应时间会随着流量分布出现不同程度的延迟。而热管理系统耦合了热力学过程与流体力学过程,系统内节点众多、相互耦合,表现高度的异质性与复杂性,常规的动力学建模方法难以表征其动态特性,无法分析延迟效应产生原因,难以针对性设计控制系统。提出基于图论的分层(流体-热力学)内循环燃油热管理系统动力学建模方法,利用所建模型揭示响应延迟问题产生的内在机理,并量化响应模态随流动状态分布的区域特征。结果表明延迟效应产生的本质原因是内循环改变了系统动力学的拓扑结构,增加了正反馈项,内循环的流量越大系统响应速度越慢。

Abstract:

Introducing an internal circulation loop boosts aircraft Thermal Management System (TMS) heat sink efficiency. However, it creates complex dynamics with flow-dependent response delays. TMS couples thermodynamic and fluid dynamic processes, featuring numerous interconnected nodes that exhibit high heterogeneity and complexity. Conventional modeling fails to capture these dynamics or analyze delay causes, hindering control design. This paper proposes a hierarchical (hydraulic-thermal) graph-based modeling method for internal loop TMS dynamics. It reveals delay mechanisms and quantifies delay zones across flow states. The results show that the fundamental cause of the delay effect is that the internal circulation alters the topological structure of system dynamics and adds positive feedback terms, and the larger the flow rate of the internal circulation, the slower the system response speed.
