Description:
The report gives results of a development study involving feasibility verification of a novel particle impactor in which the impaction surface is the interface between two opposing jets. Particles (which would impact a solid surface in a standard impactor) cross the interface between the aerosol-laden gas and a previously particle-free gas, are entrained in the latter, and are conveyed out for analysis. Work consisted of an initial literature search and analysis to determine the likelihood of success, followed by design, fabrication, and testing of a laboratory unit. A good particle separation capability was demonstrated. Upon completion of the laboratory tests, a design effort showed the feasibility of a staged in situ particle monitoring subsystem to give semicontinuous (nominal 1 minute cycle time) output of particle size distribution, among other applications.
