The main characteristics of diffusion flames formed on a liquid fuel surface with a parallel oxidizer flow have been studied both analytically and experimentally. In the present paper fuel burning rates and temperature and velocity profiles have been determined for various liquid fuels. Experimental results arc in good agreement with the theoretical model previously developed by one of the authors, except for the velocity profiles at low air velocity, which display a pronounced overshoot close to the flame zone. Present results also indicate that main flame characteristics can be controlled by means of the temperature of the liquid fuel contained in the burner and kept constant for long times. Finally. the burner studied in this research appears to be particularly suitable for the analysis of combustion kinetics.

Abstract

The main characteristics of diffusion flames formed on a liquid fuel surface with a parallel oxidizer flow have been studied both analytically and experimentally. In the present paper fuel burning rates and temperature and velocity profiles have been determined for various liquid fuels. Experimental results arc in good agreement with the theoretical model previously developed by one of the authors, except for the velocity profiles at low air velocity, which display a pronounced overshoot close to the flame zone. Present results also indicate that main flame characteristics can be controlled by means of the temperature of the liquid fuel contained in the burner and kept constant for long times. Finally. the burner studied in this research appears to be particularly suitable for the analysis of combustion kinetics.
