Physical and chemical behaviour of polydisperse droplet systems

The computer code NACRE originally describing only the physical behaviour of polydisperse aerosol systems has been extended to chemical reactions in the wet phase of droplets. At the moment data for the oxidation of SO 2 by 03 and H,02 are implemented in the code. Sample calculations are presented for the geometry of the planned large scale experiments AIDA showing the interaction between the physical and chemical processes.
