In a post-accident reactor environment, condensation of different species on the aerosol particles can occur at a rapid rate which increases the mass and volume of the aerosol particles. This change in particle properties affects both the coagulation and deposition rates of the aerosols as well as removal of the condensates (for example, the fission products). We have explored the feasibility of the Direct Simulation Monte Carlo (DSMC) technique when condensation alone occurs, and when both condensation and coagulation occur simultaneously. We have simulated several test cases and compared the DSMC results against the analytical results. We have found that the DSMC results agree well with the analytical results for all the test cases simulated. (c) 2007 Elsevier Ltd. All rights reserved.
