Formation of Mixed Molecular Clusters in Free-Jet Expansions

Abstract

To determine the concentrations of jet engine pollutants in the stratosphere, it is necessary to obtain information concerning the molecular clustering characteristics of pollutant species. In the present investigation, a simulation of jet engine exhaust emissions has been accomplished by expanding various gas/water mixtures from a molecular beam source and mass analyzing the resulting molecular beam. It was found possible to produce ionic clusters containing various combinations of N2, CO2, SO2, CH4, and H2O.
