中文摘要	基于一维两相四方程漂移流模型,并考虑加热段欠热沸腾、上升段冷凝以及上升段闪蒸的影响,采用数值模拟的方法对5 MW低温核供热堆热工模拟回路(HRTL-5)的轴向空泡分布进行模拟计算,分析HRTL-5轴向参数分布的特性及其参数效应。结果表明:1)在HRTL-5条件下,考虑欠热沸腾、冷凝、闪蒸等因素影响的计算结果更接近实际情况;2)是否考虑加热段的欠热沸腾对于加热段出口的空泡份额以及出口的状态确定有重要影响;3)冷凝过程对于闪蒸区以及自然循环驱动力的计算有一定的影响;4)闪蒸对低压低干度自然循环系统轴向空泡份额的分布有重要影响,尤其在低压情况下。; Based on the one-dimension two-phase drift flow model,along with the consid- eration of the subcooling boiling in heated section,the condensation and the flashing in the riser,the simulation of the axial distribution of void fraction in natural circulation in HRTL-5 was performed.The characteristic of the distribution of void fraction and its parameter effects were analyzed.The results showed that the drift flow model along with the consideration of subcooling boiling,the condensation and the flashing was more suitable for describing the simulation of the distribution of void fraction in HRTL-5. Whether taking the subcooling boiling into account or not was very important for the calculation of the void fraction and the confirmation of the status at the exit of the heat- ed section.Besides,there was some influence on the calculation of the flashing zone and the driven force of natural circulation with or without the consideration of condensation. Finally,the flashing can make great influence on the calculation of distribution of the void fraction,especially under the lower pressure condition.
