Particulates and Aerosols Sampling from Combustor Rigs using the UMR Mobile Aerosol Sampling System (MASS)

Abstract

Over the past 10 years a compact mobile aerosol sampling and characterization facility has be 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 microns, and operational methodology will be described. In particular, its application will be evidenced with data from a recent measurement campaign where the system was used to characterize the particulates present in the combustor rig for an advanced low NOX engine concept being developed for NASA by Pratt and Whitney. Data on particulate concentration, size distribution and hydration properties will be presented and compared with previous measurements from other jet engine exhaust samples collected at the exit plane of the exhaust nozzle.
