Studies on high pressure and unsteady flame phenomena. Annual report, 15 April 1993-14 April 1994
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. During the reporting period progress has been made in the following projects: (1) a theoretical and experimental study of unsteady diffusion flames; (2) a computational and experimental study of hydrogen/air diffusion flames at sub- and super-atmospheric pressures; (3) an asymptotic analysis of the structure of premixed flames with volumetric heat loss; (4) asymptotic analyses of ignition in the supersonic hydrogen/air mixing layer with reduced mechanisms; (5) a new numerical algorithm for generating the ignition-extinction S-curves. A total of three reprints are appended.
