Aerodynamic Aerosol Concentrators

Abstract : Overview: Detector Considerations Response threshold on the order of 104 particles. Air handling system is a major power consumer in the detector system. Goal: Develop High-Throughput, Low-Power Bioaerosol Concentrators. Slot-Nozzle Virtual Impactors Smaller nozzle dimensions reduce power consumed for fixed cutpoint and flow rate concentrator. Slot nozzles are easier to manufacture for high through-put and resist fouling to a greater degree than round nozzle virtual impactors. Prototype Devices LSVI and CSVI Units Wall loss mechanisms Misalignment of acceleration and receiver nozzle. Receiver nozzle profile. Acoustic resonance. Experimental Data. Research Plans.
