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.
