【摘要】 采用凝汽器壳侧流场与传热特性计算软件,对大亚湾核电站凝汽器管束排列方式进行了二维数值分析,表明其排管方式存在显著的缺陷。计算表明:在布管空间不变的条件下,采用德国Balcke-Dürr公司的管束排列方式,其传热性能有很大的改善。图14表1参3更多还原

【Abstract】 Daya bay nuclear power station condenser’s bundle arrangement is analyzed through two-dimension numerical calculation program of steam flow field and heat transfer in condenser. The result indicates that the present bundle arrangement has some salient disadvantages. The new type bundle arrangement of German Balcke-Dürr Company has also been analyzed in the same condition as the present bundle arrangement, it makes great improvement in many ways.
