气溶胶迁移规律研究进展

Abstract

Abstract: With the development of nuclear power, radiation hazard caused by transuranic nuclide aerosol becomes the problem that cannot be ignored. How to find the aerosol migration rules is the key to solve this problem. The research results on influence the act of aerosol migration and migration rules are synthetically analyzed in this paper, aerosol migration is found to be primarily affected by the characteristics of aerosol’s self, carrier airflow state, and the influence of external physical field. The research about the influence of aerosol's self characteristics on migration focuses on aerosol characteristics on sedimentation, diffusion and coagulation in process of migration, which belongs to the study of aerosol migration rules under ideal conditions. The research about the influence of carrier airflow state on aerosol migration focuses on the movement state of carrier airflow, and the two-phase flow between carrier airflow gas and aerosol particles, which mainly describe the distribution of aerosol particles in carrier airflow under carrier airflow state. The research about influence of external physical field on aerosol migration focuses on temperature field, magnetic field, electric field and humidity field, which is suitable to describe the aerosol migration state in the actual process. Through analyzing influential factors of aerosol migration, it is considered that aerosol migration behavior under multi-factor, migration rules and model of aerosol under multi-physical field coupling have not been studied.
