【摘要】 基于混合流模型的质量、动量和能量守恒方程,采用可移动边界法建立了压水堆螺旋管式直流蒸汽发生器的稳态和动态分析模型。模型将二次侧传热区域分为预热段、蒸发段和过热段,且考虑了缺液区传热。通过对国际革新与安全反应堆(IRIS)螺旋管式直流蒸汽发生器的模拟,对模型进行了验证。结果表明,本文所建立的稳态和动态模型合理,稳态计算结果与设计值符合良好,动态仿真符合热工水力学及其定性机理分析结果。更多还原

【Abstract】 Based on the conservation equations of fluid mass,momentum and energy,a thermal-hydraulic model for helical-coil tube type once-through steam generator(HCSG)was developed by movable boundary method.The heat transfer control volume was divided into three segments:economizer,evaporator and superheater regions,and the mist evaporation region was taken into account.The thermal-hydraulic model was evaluated against the data of the HCSG of the International Reactor Innovative and Secure(IRIS).The steady state results of the new model are in good agreement with the design parameters of IRIS,and the dynamic simulation results are suitable for the thermal-hydraulic analysis of HCSG.更多还原
