Analytical and Experimental Study of Turbulent Methane-Fired Backmixed Combustion.

Abstract

Numerical predictions of the backmixed flowfield of a methane-fired laboratory combustor are compared to experimental observations. The goal is to clarify the mechanisms responsible for pollutant formation in continuous backmixed combustion and to improve predictive methods. The numerical description adopts a simplified effective viscosity model and a two-step kinetic reaction scheme for the methane oxidation. A reaction mechanism to account for the production of nitric oxide is also considered. Laser Doppler velocimetry is used to exerimentally measure velocity profiles in the flowfield. Conventional gas sampling techniques are to measure species concentration profiles.
