Paper Title:
Experimental Study on Pressure Effect during the Generation and Growth of Sulfuric Acid Aerosol
  Abstract

Formation of sulfuric acid aerosol form a binary mixture of sulfuric acid and water is one of the most important process of secondary particles formation in troposphere, which can seriously affect the atmospheric radiation balance and climate change directly or indirectly, therefore, in this research, secondary aerosol generation by photo oxidation by UV of SO2 containing model air in a flow reactor was investigated experimentally, and the particle size distribution was measured by differential mobility analyzer and Faraday cup electrometer (DMA-FCE) system. Experiments were carried out at various ambient pressure and residence time, and the temperature of reactor was kept at 25, the experiment aims to find out the impact of pressure on this system. The results showed that in low pressure, the growth of aerosol particles was enhanced due to the increase of Brownian coagulation coefficient.
