摘要
应用通用计算流体力学软件STAR-CD,对中国实验快堆(CEFR)堆芯出口区域进行详细的三维热工流体数值模拟,研究了该区域内钠搅混状况,获得了堆芯出口流场和温场。计算结果为堆芯出口温度测点布置的合理性评价和分析温度波动和流动扰动对控制棒导向管的影响等问题提供依据和参考。
Detailed 3D thermal-hydraulic numerical analyses to the fuel zone outlet are actualized with the STAR-CD CFD code. The performance of sodium mixing is studied and detailed velocity and temperature distribution are obtained in this region which will offer foundations and references to study the rationality of temperature monitoring-spot arrangement and to assess the effect of temperature fluctuations to control rod guide tubes in this region, and so on.
