AEROSOL MECHANICS

ENV 6130, Spring 2008
Time and Location: Periods 7-8, BLK 415

Aerosols, which are particles suspended in the air, are omnipresent:

  • smoke from power generation, cigarette, forest fire;
  • atmospheric aerosols causing ozone depletion, reduced visibility;
  • rain, snow, cloud, fog;
  • respiratory deposition: particles containing toxic metals, PAH causing adverse health effects;
  • drug delivery through respiratory system;
  • production of innovative materials for next generation using aerosol processes

 

Certain aerosols cause significant health and environmental problems while others improve the quality of our life. To prevent the formation of undesired pollutants or to produce materials of desired properties, it is important to understand the mechanics of aerosols. In this course, the following topics will be covered to help you understand fundamental aerosol mechanics so that you can "manipulate" your aerosols:

  • Aerosol Characterization: Particle Size Statistics, Microscopic Size Measurement, Moment
  • Transport Properties: Inertial Impaction, Diffusion, Electrical Migration, Thermophoresis
  • Optical Properties
  • Aerosol Dynamics: Coagulation, Condensation, Nucleation, GDE
  • Aerosol Measurement & Generation
  • Application: Respiratory deposition, atmospheric aerosols, nanoparticle synthesis
