摘要

摘要: 利用三维计算流体力学程序GASFLOW分析了气溶胶的再悬浮行为。通过拉格朗日粒子模型计算得出再悬浮率，并将所得结果与集总参数程序ASTEC的计算结果与国际标准例题中的STORM试验台架测试的SR11试验结果进行对比。计算结果表明，GASFLOW程序能较好地模拟气溶胶的再悬浮行为，且相对于集总参数程序而言，能清晰直观地展示不同时刻气溶胶的位置分布，可为压水堆核电站严重事故条件下的气溶胶行为分析提供参考。

Abstract: The aerosol resuspension behavior was simulated by three-dimensional computational fluid dynamics program GASFLOW. The resuspension rate was calculated by Lagrangian particle model and compared with the results obtained from the calculation of the lumped parameter program ASTEC and the test results obtained from STORM series tests-SR11 in the international standard problems. The results show that GASFLOW program can simulate the aerosol resuspension behavior well. Compared with lumped parameter program, GASFLOW program can clearly and intuitively display the aerosol position distribution at different time, which can provide reference for aerosol behavior analysis under severe accident conditions of pressurized water reactor nuclear power plant.
