摘　　要：文章构造盘管直流蒸汽发生器(SG)两相段计算模型。采用四方程漂移流模型,对盘管直流SG的两相段传热进行进一步划分。选用适当的结构关系式和传热关系式,用数值方法进行了盘管SG的稳态分析。A two-phase section calculating model for once-through helical-coiled steam generator was developed. Nonequiliburium four-equation drift-flux model was adopted and the two-phase flow section of once-through helical-coiled steam generator was divided into more subsections. Suitable structure property equations and heat transfer equations were adopted, and steady state analysis for once-through helical-coiled steam generator was carried out by numerical method.
