抄録

In this study an experimental setup was developed that enabled us to investigate effects of pressures on generation and growth of sulfuric acid aerosol by photo-oxidation of gaseous SO₂. Changes in particle size distributions of generated aerosol at reduced and standard atmospheric pressures were measured. Particle size distributions of generated sulfuric acid aerosols were measured at the initial SO₂ concentration of 1 and 5 ppm and mean residence time of 2.31, 4.62 and 9.25 s, and the effects of pressure on the growth of sulfuric acid aerosols were investigated. The growth of sulfuric acid aerosol by coagulation as well as condensation was enhanced at reduced pressure due to the increase in particle diffusion coefficient in both transition and continuous regimes.
