Impact of Operating Regime on Aviation Engine Emissions: Modeling Study

摘要

This work is focused on the numerical analysis of pollutant formation in an aviation gas turbine engine at different values of power setting. The analysis is conducted on the basis of a comprehensive approach treating the reactor net model for description of nonequilibrium chemical processes inside the combustor and the quasi-one-dimensional model to compute the evolution of species concentrations in the postcombustor flow. Special attention is paid to the study of the formation of volatile aerosol precursors: sulfuric and nitrous acids and organic compounds.
