摘要: 根据临界热流密度Benchmark本体试验，研究定位格架间距对临界热流密度大小和发生点以及发生临界通道的热工水力参数的影响。分析结果表明，随着定位格架间距的增大，临界点向下一个定位格架上游移动，临界热流密度增大，发生临界通道的出口质量流速减小。
Abstract: Based on the ontology test of Benchmark, it was studied that how the positioning lattice spacing influenced on the critical heat flux and its occurrence point as well as the thermal hydraulic pa-rameters of the critical passage. The results show that as the distance between the positioning lattice increases, the critical point moves upstream of the next positioning lattice, the critical heat flux increases, and the exit mass velocity of the critical passage decreases.
