Depending on meteorologic conditions, aerosol formation in the atmosphere is better approximated, but never fully simulated, by smog-chamber studies under either static (batch-reactor) or dynamic (flow-reactor) conditions.

Badger and Dryden (1939) studied aerosol formation in batch and flow reactors. They were interested in the aerosol that forms in coal gas which also contains trace amounts of nitric oxide. The nitric Oxide reacts with diolefins in the coal gas, such as butadiene and cydopentadiene. to form products of low vapor pressure. These condense and produce a sticky aerosol present at concentrations usually less than 0.5 mg which may foul the gas transfer system. 

The experiments were made in a 10-ft- gas holder. In the flow reactor studies, a mixture of NO in nitrogen wa.s added at a constant rate to a stream of coal gas entering the holder. Aerosol samples were withdrawn from the center of the gas holder, and the particles were... 

Hot wall reactors involve aerosol precursor synthesis (usually aerosols of liquid droplets) and the subsequent decomposition in a high-temperature flow reactor in order to form the desired aerosol products (usually aerosols of solid particles). This method has been used to prepare soot particle aerosols and also a variety of metal oxide aerosols, including aerosol phosphors [47]. 

Figure 13-4. Deposition rate variations versus precursor concentration in the atomized solution, for aerosolr-gel deposited Si02 films (a), and MTPS-based hybrid orgmic/inorgmic Si02 films (b). The deposition rate is defined as the ratio of the film thickness, measured after soT-gel transformation, to the aerosol sweeping tune (deposition time). Films were deposited using a horizontalflow (a) and a vertical flow reactor (b).
