摘要:

核电应急柴油罐中柴油在长期存储过程中易发生变质,严重影响应急柴油机组的运行效率和可靠性,给核电安全运行带来风险。为确保柴油使用时的品质达标,需要定期对其进行过滤和调和乃至使用添加剂调和。因此,基于FLUENT仿真技术和MATLAB智能算法,提出了一种融合遗传算法和计算流体动力学(CFD)仿真的高效、高精度的应急柴油调和优化设计方法。该方法先通过CFD仿真对油品的调和过程进行模拟分析,再结合遗传算法完成全局寻优,旨在借助遗传算法的全局寻优能力优化应急柴油调和方案,使监测点的柴油在最短时间内满足调和要求。该模型的建立,不仅提升了调和过程的效率和精度,还缩短了调和时间,为应急柴油机组的运行可靠性和效能提供了有力保障。

Abstract:

Diesel fuel stored for long periods in emergency diesel tanks at nuclear power plants is susceptible to deterioration, potentially compromising the operational efficiency and reliability of emergency diesel units and posing risks to nuclear power plant safety. To maintain fuel quality, periodic filtration and blending, with additives when necessary, are required. Accordingly, this study proposes an efficient and accurate optimization method for emergency diesel conditioning that integrates computational fluid dynamics (CFD) simulations in FLUENT with a genetic algorithm implemented in MATLAB. The conditioning process is first simulated and analyzed using CFD, after which the genetic algorithm performs global optimization to determine a conditioning scheme that enables the monitoring points to meet the blending requirements in the shortest possible time. The proposed model improves the efficiency and accuracy of the conditioning process while reducing conditioning time, thereby supporting the operational reliability and performance of emergency diesel units.
