【摘要】 随着舰船大型化、现代化和智能化发展，对其动力系统运行策略的复杂多样性、灵活性等提出更高要求；构建精准的动态仿真模型有助于其运行维护、控制逻辑优化以及现场事故反演等，可有效保证舰船安全运行和高效作业。为了提升仿真模型精度，首先筛选出系统中的非标准异构件(其通流特性通常不满足设计指标)；之后采用三维CFD方法模拟其真实运行状态下的内部流场和流阻特性；进而搭建耦合接口，实现一维系统仿真与三维CFD计算之间的数据传递和实时更新；最后将搭建的多维动态仿真模型应用到燃油输运系统中，能够成功预测由于管网系统突然启动和流体惯性作用下的压力波动，总压与流量预测差别不超过10%。在此基础上，考察了非标准异构件对系统不同支路流量分配的影响，并根据仿真结果对燃油输运系统提供运行策略优化方案，提高了舰船燃油系统对舰载机等的供油效率。更多还原

【Abstract】 As naval vessels advance towards gigantism, modernization and intelligence, there is an escalating demand for intricate,diversified and flexible strategies in their power system operations. Constructing accurate dynamic simulation models aids in operation maintenance, control logic optimization and real-time accident reenactments, which can ensure both safe and efficient vessel operations.To enhance the accuracy of the simulation model, non-standard heterogenous components within the system are initially identified.The three-dimensional CFD method is then employed to simulate the real-time internal flow field and flow resistance characteristics under actual operational states. Subsequently, an interface is constructed to facilitate data transfer and real-time updating between onedimensional system simulations and three-dimensional CFD computations. The multi-dimensional dynamic simulation model developed in this study, when applied to the fuel transport system, successfully predicts pressure fluctuations due to the sudden initiation of fuel pumps and fluid inertia effects, with a total pressure and flow rate prediction deviation not exceeding 10%. Based on this, the study explores the impact of non-standard heterogenous components on the flow rate distribution of different system branches. The simulation results guide optimization strategies for the fuel transport system, thereby enhancing the fuel supply efficiency of the naval vessel.更多还原
