Chain-aggregate aerosols in smoke from the Kuwait oil fires

摘要: Electrooptical scattering was used to detect aggregated particle chains in the smoke from Kuwait oil fires. Nonsphericity detected by change light brought about induced alignment of particles when subjected a pulsed, bipolar electric field. Measured parameters included steady state enhancement for complete orientation particles, and rotational diffusion constant, calculated time required relax random after field removed. Chain aggregates soot formed within seconds combustion those fires producing black smoke. These agglomerated some extent near fires, but then remained relatively unchanged several hours travel downwind. Very little nonsphericity plume white smoke, which consisted primarily salt brine products emitted along with oil. 10 refs., 4 figs., 1 tab.
