Effect of chemical and nuclear reactions on aerosol transport
The inclusion of the effects of chemical and nuclear reactions on aerosol transport is a complex problem in numerical simulation. Heterogeneous chemical reactions occur at the interface between the surface of a particle and the suspending medium, or between the surface of a wall and the gas in the aerosol. Homogeneous chemical reactions occur within the aerosol suspending medium, within a particle, or on the wall. Both types of reactions may include a phase change. Nuclear reactions occur in the same locations as homogeneous chemical reactions. These spontaneous transmutations from one elemental form to another occur at greatly varying rates. Several basic elements may be undergoing spontaneous transmutation, each of which may also result in a phase change. Particles in an aerosol agglomerate due to several mechanisms. These particles also change size due to condensation and other related processes such as the effective condensation that occurs from a phase change resulting from chemical and nuclear reactions. Particles are also removed from the aerosol by various deposition modes. This paper presents an approach to include all these mechanisms in a simulation algorithm with special emphasis on the effect of both chemical and nuclear reactions on the model development.
