摘要
在三维计算流体动力学(CFD)安全壳程序GASFLOW中开发了严重事故条件下的气溶胶再夹带模型。在空气-蒸汽和纯蒸汽两种安全壳大气环境下分析了安全壳卸压导致的气溶胶再夹带现象,并将所得结果与相同条件下的Ishii模型计算结果及REVENT试验数据进行对比。计算结果表明,开发的气溶胶再夹带模型能够较好地模拟气溶胶的再夹带行为。
An aerosol entrainment model under severe accident conditions was developed in the threedimensional computational fluid dynamics(CFD)containment program GASFLOW.The phenomenon of aerosol entrainment caused by containment pressure relief was analyzed in two containment atmospheres,air-steam and pure steam,and the results were compared with Ishii model calculation results and REVENT test data under the same conditions.The calculation results show that the developed aerosol entrainment model can well simulate the aerosol entrainment behavior.
