Optimum Design of Steam Generator

College of Nuclear Science and Technology, Harbin Engineering University, Harbin, 150001, China

摘要: 以立式U形管自然循环蒸汽发生器(SG)为例,提出一种自主开发的SG评价模型和改进复合形优化算法。在考虑多种热力性能和几何结构约束的条件下,对U形管自然循环SG结构进行最优化设计。结果显示:优化方案与原型相比,其重量减小了16.4%,体积减小了16.3%,优化效果显著。

Abstract: Taking the vertical U-tube natural circulation steam generator as an example,this paper puts forward the evaluation model of steam generator as well as the improved complex algorithm.The optimization design under the constraint conditions of various thermal performance and geometry construction is carried out.The results show that the optimal weight is 16.4% less than the original,and the volume is 16.3%.The optimization effect is very obvious.
