Abstract:

Non-stationary mathematical model of bioaerosol dynamics is considered. It is based on nonlinear integral-differential equations describing coagulation, condensation, and evaporation processes. Unconditionally positive numerical schemes for transformation problem is presented. The algorithm is based on discrete analytical approximations using fundamental solutions of local ajoint problems. The model was numerically compared with the models describing individual mechanisms in its composition. The relative contribution of each mechanism in the overall dynamics of aerosol populations is investigated based on numerical experiments.

Keywords:

mathematical modeling, aerosol populations, impurities transformation, coagulation, integral-differential equations
