摘　　要：本文提出了基于多孔介质方法,铅铋螺旋管式直流蒸汽发生器开展数值模拟,并通过与三维数值模拟结果的对比验证了多孔介质模拟方法的正确性。基于此方法,对给定工况条件的铅铋螺旋管蒸汽发生器开展了设计研究。在1.5 MW功率目标下,发现四层螺旋管的布置方式具有最优综合性能。在此基础上,通过综合性能评价指标对不同工况条件下不同几何参数的螺旋管蒸汽发生器开展性能评价,并运用多元线性拟合探究在工况以及几何范围内综合性能最佳的几何模型,最高性能提升达到3.37%。本研究为铅铋螺旋管式直流蒸汽发生器数值模拟及设计优化提供新的方法参考。In this paper,a numerical simulation method of the Lead-bismuth Helical Coil Once-through Tube Steam Generator(LHCOTSG)based on the porous medium method is proposed.The correctness of the simulation method is validated by comparison with three-dimensional numerical simulation results.Based on this method,a LHCOTSG with a given working condition was designed and studied.Under the power target of 1.5 MW,the arrangement of four-layer helical tubes has the optimal comprehensive performance.On this basis,the performance of LHCOTSG with different geometric parameters under different working conditions was evaluated by comprehensive performance evaluation index.The multivariate linear fitting method is adopted to obtain the best geometric model within the range of working conditions and geometric parameters.The highest performance was improved by 3.37%.This study provides a new method reference for numerical simulation and design optimization of LHCOTSG.
