摘　　要：以B&W公司直流蒸汽发生器(OTSG)为对象,基于仿真支撑软件APROS平台中的基本模块,建立了图形化的直流蒸汽发生器模型;利用不同的APROS两相流计算模型进行仿真,对比分析后选取六方程计算模型;将2种模拟工况下的仿真结果与压降和传热系数经验关系式的计算结果进行对比,根据对比结果修正模型的压降和传热系数;将设定工况下的稳态及动态仿真结果与国内外实验数据对比,验证了本文模型的准确性。Taking a once-through steam generator designed by Babcock & Wilcox as the study object, a graphical model was designed, based on the basic module of supporting platform APROS. Based on the simulation with the different two-phase flow calculation model, after comparative analysis, a six-equation model was selected for calculation. The simulation results from different working conditions are compared with the results of empirical formula for pressure and heat transfer calculation, and the fluid pressure and heat transfer efficiency in the model are modified. Then the steady-state and dynamic simulation results under the set working conditions are compared with the experimental data published abroad to verify the accuracy of the model.
