Aerosol Collection Technology

"Phoenix Analysis and Design Technologies (PADT) proposes to develop two particle collection and concentration devices, one designed for 100 LPM and another for the 600 LPM flow rate. Both configurations will be optimized for collection efficiency, powerconsumption, size, cost, and weight. The proposed solution is comprised of a custom inlet, a novel collection chamber, and a continuous gas-to-liquid concentration mechanism. An autonomous, `point-into-the-wind', iso-kinetic inlet is planned to maximizethe inlet collection efficiency for difficult sampling conditions, such as shipboard sampling. A collection mechanism is proposed that relies upon well-understood physics and will exhibit the combined behavior of an impactor, cyclone, and centrifuge, allin one system, with minimal additional pressure loss. The gas-to-liquid concentrator will consist of a liquid injection and recovery system. Both designs will also require a preconditioning stage to remove large particles (i.e., insect, crustal matter,etc.). To meet these objectives, PADT will draw upon recent successes in system-level modeling, and a historical expertise in applying Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) to critical components. Leveraging PADT'sexperience and current leading-edge position in rapid prototyping technologies should allow for a single, representative, `proof-of-physics' prototype near the end of Phase I.
