摘　　要：采用法国TRIO-VF反应堆热工水力计算程序对反应堆流场进行数值计算,其几何模型与实验模型完全相同,获得了满意的结果。采用国内外最先进的PIV粒子成像测速仪对反应堆流进行测量,获得了上腔室周边流场和上封头流场速度分布与压力分布以及吊篮上法兰喷嘴阻力系数。对测量结果进行了详细的分析讨论,并将计算结果与实验结果进行了对比分析。结果表明,上腔室和上封头内流场的速度和压力均相符较好。In this research, numerical simulation has been completed before test. In the computation, TRIO-VF code introduced from CEA is employed in the calculation, and geometric model is the same as test model. The satisfactory computational results are achieved. In the test, PIV measuring equipment is used to measure flow rate in upper plenum and closure head. The pressure in upper plenum and closure head has been measured. Due to the comparison between results obtained by two methods, the coincident flow rate and pressure in upper plenum and closure head have been achieved.
