- Abstract
- Given the increasing interest in air pollution, several technologies to measure black carbon (BC) aerosolparticles have been developed. As most BC aerosol particles are smaller than 1 μm, it is necessary topre-separate the particles by size before a BC measuring instrument samples the aerosol particles. In thisstudy, a miniature cyclone separator for portable BC measuring instruments was developed. A numericalapproach was used to design the miniature cyclone separator with operating flow rates of 50, 100, or 150mLPM, and then a prototype cyclone separator was manufactured for experimental validation. The numericalresults of the cut-off size and pressure drop of the miniature cyclone separator agreed well with theexperimental data. The cut-off sizes of the miniature cyclone separator were determined to be 2.9, 0.94, and0.63 μm for operating flow rates of 50, 100, and 150 mLPM, respectively. Thus, the miniature cycloneseparator is suitable for use as a sampling inlet for the portable black carbon measuring instrument to sampleBC aerosol or PM2.5 aerosol.
