This course will introduce key concepts of aerosol science and engineering and the fundamentals of particulate matter transport in environmental and engineered systems. The key topics covered in the course are: Fundamental properties of particulate systems - physics of aerosols, size distributions, mechanics and transport of particles: diffusion, inertia, external force fields. Visibility and light scattering. Aerosol dynamics - coagulation, nucleation, condensation. Applications to engineered systems: Nanoparticle synthesis, atmospheric aerosols, combustion aerosols, pharmaceutical aerosols.
