Particulates and aerosols characterized in real time for harsh environments using the UMR mobile aerosol sampling system (MASS)

Abstract

Over the past 10 years a compact mobile aerosol sampling and characterization facility has been developed and operated by the Cloud and Aerosol Sciences Laboratory at UMR. In this presentation its measurement capabilities which include: total number density, size distribution and hydration property determination in real time for aerosols/particles greater than 0.007 µm, and operational methodology will be described. Its application in harsh environments will be evidenced with data from recent measurement campaigns where the system was used to (1) sample and characterize particulates from the supersonic reacting flow of a high energy chemical laser, (2) detect the presence of an invisible jet engine exhaust plume minutes after the aircraft had passed and discriminate the recently generated jet engine aerosol from ambient background carbonaceous aerosol and (3) characterize engine and fuel specific aerosol sampled during jet engine testing.
