摘　　要：应用欧拉两相流最新CFD模型技术对某溶液反应堆台架模型堆芯内气液两相流动传热进行了数值分析。堆芯内离散相气泡被考虑为不同直径的组分,摒弃了传统均一离散相的假设(即假设所有气泡为同一直径和形状),把应用群体平衡理论建立起来的MUSIG(Multiple-Size-Group)模型考虑到CFD分析中。MUSIG模型用于分析堆芯内气泡的流动和大小分布。将气体离散相采用分为5组不同直径的气泡直径。分别采用Luo and Svendsen和Prince and Blanch模型描述不同直径气泡组之间的破裂和聚合。模拟结果与台架实验结果吻合较好。The air-liquid both phases flowing heat transter in the solution reactor framwork model core using Ora both phases flowing letely CFD model technology is numerically analysed. The bubbles of separated phases in the reactor core are considered as difference diameter forms and the supposition of conventional uniform separated phases is discarded. The MUSIG model which set up by means of mass balance theory is considered as the CFD analysis. The MUSIG model is used for analysing the bubble flow and size distribution. Separated phases air is divided into 5 groups difference diameter bubbles and separately adopts Luo and Svendsen as well as Prince and Blanch model to describe the break and accumulation of bubbles between difference diameter bubble groups. Simulation result well correspond with framework experi-ment result.
