针对鱼雷Li/SF_(6)闭式循环动力系统锅炉反应器复杂物理化学过程中参数耦合、参数时变造成的系统稳定域度小等问题,文中基于传热学理论,采用分段式处理方法,建立了锅炉反应器螺旋换热管流动换热模型,对传热过程进行了数值仿真,探讨了非对称加热条件下锅炉反应器入口工质温度、出口工质温度、出口工质压力、出口工质流量等参数的变化对蒸汽生成过程的影响规律。研究结果可为系统性能仿真和调节控制优化,提升系统稳定域度提供支撑,为锅炉反应器的工程设计、优化和试验验证提供理论参考,对同类装置的研究和设计也具有一定的参考价值。

To solve the small stability domain problems caused by the coupling of parameters and the time-varying parameters in the complex physicochemical process of a boiler reactor used in a torpedo Li/SF_(6) closed-cycle power system,based on heat transfer theory,the heat transfer model of a helical exchange tube in a boiler reactor was established using segment processing.A numerical simulation of the heat transfer was conducted,and the influence of inlet-working fluid temperature,outlet-working fluid temperature,outlet-working fluid pressure,and outlet-working fluid flow on the boiler reactor steam generation process under asymmetric heating conditions was explored.The results can provide support for the system performance simulation,control optimization,and stability domain improvement,and provide a theoretical reference for regulation control for the design,optimization,and experimental verification of boiler reactors,and have certain reference values for the research and design of similar devices.
