Characterization of One- and Two-Dimensional Homogeneous Combustion Phenomena in a Constant Volume Bomb

A combustion bomb has been used to compile a comprehensive set of well-characterized experiments which may be used to validate computer models of IC engine combustion. Extensive variations of experimental conditions allow the kinetics and fluid mechanics in the codes to be independently evaluated. Thermodynamic properties of the swirling, uniform precombustion mixture are characterized by measuring pressure, temperature distribution (with thermocouple probes), velocity/turbulence (with laser Doppler velocimetry) and equivalence ratio. Combustion diagnostics include pressure histories, high-speed laser shadowgraph filming, flame position determined with a laser refraction technique, and time- and space-resolved density using laser Rayleigh scattering.
