Studies on High Pressure and Unsteady Flame Phenomena.

Abstract

The objective of the present program is to study the structure and response of steady and unsteady laminar premixed and nonpremixed flames in reduced and elevated pressure environments through (a) non-intrusive experimentation, (b) computational simulation using detailed flame and kinetic codes, and (c) asymptotic analysis with reduced kinetic mechanisms. For the three year period supported by the grant, the following projects were completed and reported in nineteen journal- class articles: (1) Studies on unsteady flames; (2) Studies on high-pressure flames; (3) Re-examination of the counterflow technique in flame speed determination; (4) Asymptotic structure of premixed methane/air flames; (5) Theories on flame extinction; (6) Numerical algorithm for generating S-curves; (7) Thermophoretic effects on seeding particles in LDV measurements of flames; and (8) Review activities.
