摘　　要：为满足 10MW高温气冷堆 (HTR 10 )控制系统分析设计的需要 ,分析了HTR 10螺旋管式直流蒸汽发生器内两相流动和传热的实际过程 ,根据建模的要求和可能获得的结构数据 ,选择四方程漂移模型来描述螺旋管内两相流现象 ;经过仿真试算与实验总结 ,确定了模型中关键的结构关系式和传热工况的判断逻辑 ,以此为基础 ,建立了可反映直流蒸汽发生器在正常功率运行范围内动态特性的动态数学模型。通过对典型工况的动静态仿真计算和研究分析 ,表明所得的结果与理论定性分析和实验吻合 ,从而证明了该模型的正确性。In order to design and analyze control system of HTR 10, It is analyzed that the two phase flow and heat transfer procedure inside the helical coils of one through steam generator of HTR 10. Based on the requirement of model and structure property equations, the four equation drift flux model is selected to describe two phase flow in the helical coils. The simulating and experimenting determined the main structure property equations and judgement logical of heat transfer situation. And the dynamic mathematical model that established for steam generator of HTR 10 could describe steam generator’s dynamic characteristic at the normal running range of reactor.
