Particulate size distribution of exhaust gases for a micro gas turbine jet engine

摘要

This work investigated the particulate number concentrations and size distributions of exhaust gases emitted from a micron gas turbine jet engine. A SMPS was used for measuring particles sized from 5 nm to 160 nm. The engine exhaust was directed into a duct, where the ambient air was entrained to dilute the exhaust gases. Particulates were measured for number distribution, median, mean and mode size as a function of throttle settings.
