Kinetic Double-layer Modelling of Aerosol Surface and Bulk Chemistry
Abstract
the mass transfer and chemical reactions at the surface and inside most aerosol particles. The K2-SUB is applied to the
atmospheric heterogeneous chemical model system: the interaction of ozone and oleic acid. It can be used to model volatile
and non-volatile substances at the gas-particle interface and inside the particle, time and concentration distribution, as well as
surface concentration and gas absorption coefficient. Modelling the reaction of oleic acid particles- a proxy system for kitchen
exhaust gas- with the atmospheric oxidant ozone (O3) provides evidence that when the particle size of oleic acid gradually
increases, the decay time of oleic acid in ozone is longer. K2-SUB is less sensitive to the surface reaction rate coefficient and
the bulk reaction rate coefficient but is sensitive to the bulk diffusion coefficient of ozone and initial surface accommodation
coefficient of ozone.
