Combustion emission of soot and pollutant gas species contributes to poor regional air quality near emission sources and to climate change. It is important to understand the formation mechanism and time evolution of these pollutants inside the combustion engine, through detailed modeling of combustion chemistry and microphysics as well as comparison with observation. In this thesis, two multi-zone gas parcel combustion engine models, one for aircraft engines and another for diesel engines, have been developed to study soot size distribution evolution and pollutant formation inside the engines as well as emissions. The models take into account size-resolved (sectional) soot aerosol …

Airborne particles which are ubiquitous in the atmosphere have profound influences on air quality, public health and global climate. On a small urban scale, vehicle-emitted nanoparticles, being one of the major sources of airborne particles, have been shown to have adverse impacts on public health. On a much larger global scale, uncertainties on nanoparticle formation in atmosphere pose an important challenge to our understanding of the indirect radiative forcing of aerosols on global climate change. To mitigate the adverse health impacts as well as better understand the climatic impacts resulting from nanoparticles, a better understanding of their formation mechanisms in …
