Study Of Soot Growth And Nucleation By A Time-Resolved Synchrotron Radiation Based X-Ray Absorption Method

Abstract

This report results from a contract tasking University of Rennes I as follows: The contractor will perform a study of soot growth and nucleation by a time-resolved synchrotron radiation based x-ray absorption method . A gaseous fuel burner will be constructed that will allow a stable flame to be produced. The burner will be mounted on an assembly that will allow the motorized movement in both a horizontal and vertical direction so that the two dimensional profile of the soot density can be measured via x-ray absorption. Associated fuel flow control equipment will be used to control and characterize flame conditions. The goal of this work therefore will be to (a) determine doped and undoped soot particle photoemission yields (b) map out the soot density structure in a heavily sooting flame using x-ray absorption and photoelectron detection and (c) determine the influence of enhanced ionization on subsequent soot growth in flames.
