Study on Distribution Characteristics of Aerosol Produced in Process of Powder Dumping in Glove Box

摘要

In this paper,aiming at the problem that the radioactive aerosol produced in the process of PuO2 powder dumping is easy to produce internal radiation hazard to operators,based on the method of computational fluid dynamics(CFD),the Eulerian two fluid model of CFD software was used to simulate the CeO2,the substitute material of PuO2.The distributions of aerosol flow field and aerosol volume fraction in glove box under the conditions of dumping speed,particle size,wind speed and inlet and outlet position were studied.
