Abstract: Results of research on major topics in aerosol science and technology are summarized. These include: (1) Formation of liquid and solid particles by nucleation and growth; (2) Influence of smoke plume/puff dispersion on aerosol growth; (3) Nonlinear interactions of laser beams with aerosols; (4) Aerosol filtration.
OBJECTIVES OF RESEARCH
The most important and usual means for production of particles less than the order of 1 m involves homogeneous nucleation in a vapor or liquid and subsequent growth by condensation/evaporation and coagulation.
This part of our research has been directed toward investigation of these processes and their incorporation in models for atmospheric dispersion of aerosols. In this section work on homogeneous nucleation and particle growth is discussed first. This begins with work on nucleation and growth of liquid aerosol followed by work on metallic aerosols and hydro-sols. Then simulation work on atmospheric dispersion is presented.
Proper design of this vaporizer was essential to obtain a steady, laminar coaxial jet from the nozzle.
Conclusions We have made a rigorous theoretical development of the equations which describe the continuum evaporation of a single droplet suspended in an inert gas, and extended this approximately to the noncontinuum regime through a slip flow analysis.
…a straightforward extension allows one to tackle the laser hole-boring problem, modeling the propagation of an electromagnetic beam through a polydispersed aerosol cloud, a problem which up to now appears to have been solved for a limiting case of a mono-dispersed aerosol.
Conclusions. Using the same size particle, increasing membrane area (or decreasing porosity) increases inertial deposition efficiency and slightly increases the diffusion efficiency.
