This thesis successfully make use of CFX in thermalhydraulic analysis of sophisticated rod bundle channel with spacer grid.
本文成功地将CFX应用于带定位格架的复杂棒束流道内冷却剂的热工水力分析计算，相关成果可为新型定位格架的设计提供理论依据，具有一定的工程应用价值和学术意义。
Make sure that the aluminum ball placed in the rod end can be moved freely. 2 holes were drilled on the plastic spacer in order to house two screws that used to hold the ball linkage.
作出肯定的是，铝球，放置在杆端关节轴承可以提出自由。二洞钻于塑胶间隔，以便向内务两个螺丝用来举行球的联系。
Three new different retangular longitudinal vortex generators spacer grid were designed, numerical simulations of the 5×5 rod bundle channel with RLVG spacer grid were conducted to investigate the mixing effects on the flow and heat transfer performance of the RLVG geometries.
论文创新性地设计了带三种冲角的矩形纵向涡发生器定位格架，并成功地对带该定位格架的5×5棒束通道流场也进行了模拟计算，经过大量计算得到了该矩形纵向涡发生器定位格架对流场搅混的流动特性和传热特性。
A test using a specially designed 3 × 3 rod bundle test section with AFA-2G structure spacer has been performed under air-water two-phase flow. The RBI optical probes were used to measure void fractions and the distribution regularity also has been analyzed.
对AFA2G3×3定位格架组成的棒束通道在空气水两相流动工况下用RBI光学探针测得了通道内的横向空泡份额分布，分析了其横向分布的一般规律。
