中文摘要	高温气冷堆堆芯流场计算是高温气冷堆系统分析模拟的重要部分。原堆芯流场计算程序在采用分块迭代方法计算耦合流场时,部分工况收敛速度慢、耗时长,甚至出现不收敛问题。基于此,本文分析了分块迭代方法的收敛性,从全局求解的思路出发,并根据堆芯流场模型的特点使用直接求解法,开发了一套用于计算高温气冷堆堆芯流场的高效全局求解方法。与分块迭代方法相比,全局求解方法的收敛性和计算效率均得到很大提高。; The flow field calculation of high temperature gas-cooled reactor(HTGR)core is an important part in HTGR simulation.The block iteration method was used in previous reactor core flow field simulation codes,but in some cases the convergence speed was very slow and convergence was hardly achieved.To improve this problem,the theory about convergence of block iteration method was investigated.Based on the idea of global solution,a highly efficient global solution method was developed for the calculation in the flow field of HTGR core.The direct solving method was employed in the new global solution method and it was based on the characteristics of the flow field model.Compared with the block iteration method,the effect and efficiency in convergence and calculation speed are significantly improved.
