Studies on High Pressure and Unsteady Flame Phenomena.

Abstract

The present study aims to gain fundamental understanding on the structure and response of steady and unsteady laminar premixed and nonpremixed flames in reduced and elevated pressure environments, and relate these understanding to the practical issues of flame extinction and turbulent combustion. The investigation herein has been conducted via the use of laser-based diagnostics, computational simulation of the flame structure with detailed chemistry and transport, and asymptotic analysis with reduced kinetic mechanisms. During the reporting period progress has been made in the following projects: (1) An analytical and experimental study of unsteady diffusion flames. (2) A computational and experimental study of the effects of thermophoresis on seeding particles in LDV measurements of flames. (3) A re-examination of the accuracy of the counterflow flame technique for the determination of laminar flame speeds. (4) Review articles written covering research performed under AFOSR support in recent years. A total of six reprints are appended.
