摘　　要：核电厂一回路系统中冷却剂流动阻力是反应堆一回路系统设计的重要依据。本文通过简单突扩流道的算例研究，阐明了流体流动产生“形阻”的原因；并通过在突扩管下游加设均匀孔板和突缩管两种阻力件结构，研究了下游阻力件对总流阻的影响，获得了总流阻增大和减小的结果。In the nuclear power plant, the flow resistance is an important factor for the design of the primary system. This paper clarified the cause of shape flow resistance by analyzing the sudden expansion flow. The influence of downstream resistance object on the total resistance was also researched by analyzing the flow resistance of the sudden expansion configuration close to a uniform pore plate or a sudden contraction configuration.

关 键 词：流体流动形阻 下游阻力件 总流阻影响
