This course will introduce key concepts of aerosol science and technology. It will cover theory of the inertial, electrical, thermal and optical behavior of gas-borne particles. Generation, collection, measurement, and dynamics of aerosols will also be discussed.
This course is designed around the goal of enabling students 1) To explain and calculate the statistics of a given particle size distribution. 2) To determine the movement of aerosols by a given transport mechanics (inertial movement, diffusion, electrical migration, and thermophoresis) and to analyze the important transport mechanisms for a given aerosol system. 3) To calculate the optical properties of a given aerosol system. 4) To derive expressions for a given aerosol system involving multiple aerosol mechanisms (nucleation, condensation, coagulation, and evaporation) and to analyze the dynamics of the particle size distributions. 5) To design systems to generate aerosols, to collect particles, and to measure particle physicochemical properties. 6) To explain the multi-disciplinary aspects of aerosol science and technology.
