| 中文摘要 | 以HTR-10中石墨粉尘聚集的重要场所蒸汽发生器(SG)为对象,通过数值计算获得SG中的流动参数,在此基础上采用Vainshtein重悬浮模型计算反应堆满功率运行情况下氦气流中石墨粉尘在SG中的重悬浮份额。结果表明,沿SG高度方向,摩擦速度逐渐增加,石墨颗粒重悬浮份额随之逐渐增大;石墨粉尘颗粒粒径越大,重悬浮份额越大;石墨粉尘随时间的重悬浮规律在SG不同区域均有短期效应和长期效应。; According to the design instruction of HTR-10, helium flow velocity along with physical parameters are calculated in cold heating period, nucleate boiling, film boiling and overheating heating region of steam generator- the most remarkable amount of graphite dust deposition equipment. Improved Vainshtein model is applied to estimate resuspension fraction. Results show that the friction velocity along with resuspension fraction increases gradually in the height direction; time-related resuspension fraction has a short-term effect, and larger graphite particles turns out to be more easily removed in the same velocity. |
