A discrete bypass particle concentrator can significantly reduce surface fouling and manufacturing cost by including bypass stages after each of concentration stages. This invention provides a means of concentrating micron-scale particles, suspended in the ambient air or from a particulate feedstock, into a highly focused particle beam. It accomplishes this using a series of concentrating lens stages in parallel with bypass stages, reducing the overall flow Reynolds number of the particle beam. At the final stage, the diverted bypass flow forms an annular sheath flow around the particle beam, minimizing beam expansion. |
