Abstract

Abstract

Based on the Integral test facility of aerosol re-suspension and re-entrainment, the experimental study on aerosol re-entrainment behavior in passive containment was carried out. By measuring the mass concentration, quantity concentration and particle size distribution of particulate matter, the motion and distribution of aerosol in the test vessel during the re-entrainment stage were analyzed. By changing the pool size, pool surface tension, particle material and concentration, the change of aerosol re-entrainment rate under different water vapor evaporation rate on unit area, different pool surface tension, different particle solubility and concentration was studied. The results show that, during the pool boiling, the re-entrainment rate of aerosol is affected by the surface tension and water vapor evaporation rate on unit area, and the particle size distribution is related to the particle material.he concentration of particulate matter solubility. The results show that, during the pool boiling, the re-entrainment rate of aerosol is affected by the surface tension and water vapor evaporation rate on unit area, and the particle size distribution is related to the particle material.
