Predicting soot emissions using advanced turbulent reacting flow modeling

Lead Research Organisation: University of Cambridge
Department Name: Engineering

Abstract

Soot is carbonaceous particulate matter formed due to the incomplete combustion of hydrocarbon fuels. Soot particles are known for their severe adverse effects to human health and the environment, thus special attention is required and particularly in the area of transportation systems.
In order to counteract these effects and design cleaner combustion devices, one should focus on the fundamentals of soot formation and oxidation in flames and their high sensitivity to operating conditions, mostly related to turbulent flow. Soot modeling has concerned the scientific community for many years so far, but a universal technique capable of predicting particle emissions in a plethora of applications has never been proposed.
The target of this research project is to address this problem by developing an updated physical modeling approach and demonstrate the improvements in predicting capability for a series of experiments. The methodology comprises of the combined use of different state-of-the-art approaches originating from turbulent reacting flow modeling, soot chemistry and aerosol science

Description The work funded through this award focused on the development of models to predict soot emissions from aero-engines. By keeping in mind both fundamental and practical aspects for industry, we have demonstrated a framework for capturing soot in realistic combustion devices, and the whole range of soot particles sizes, from the nanometre to the micrometre scale. This work is meant to help meet future regulations for particulate emissions.
Exploitation Route The methodology and the models used in this work might be used by both researchers and engineers in the industry to study and abate soot emissions.
