摘　　要：运用计算流体动力学(CFD)方法模拟研究了事故状态下有人员工作时,239PuO2微粒在不同工况下的流动特性及其粒子轨迹。结果表明:工作间关门,有利于放射性气溶胶微粒及时从排风口排出。研究结果对工作人员在事故条件下规避放射性气溶胶的危害提供了重要的参考。Flow characteristics and trajectories of ^239PuO2 particles under different work conditions in simulated accident were researched with computational fluid dynamic meth- od. The results show that the closed door of work room is propitious for radioactive aerosol to discharge from air vent. The results provide an important reference role for operational people to avoid the harm from radioactive aerosol.
