An experimental study conducted to determine the effects of lifting the flame base off the burner rim on the differences between the flame characteristics of diffusion flames from circular and elliptic burners is presented. The in-flame profiles of temperature, concentrations of fuel and combustion product species, and the mean and fluctuating components of axial velocity are presented. This study has shown that the effects of burner geometry in turbulent lifted flames are considerable only in the near-burner region. In the midflame and far-burner regions, the effects traceable to burner geometry are much weaker, contrary to those observed in the attached flame configuration. The observations are attributed to the turbulence and additional air entrainment into the jet prior to the flame base accompanying the lift-off process, which mitigate the effects of burner geometry.

Ignition And Combustion

The risk of accidental spills and possible fires is high in the storage and handling of large quantities of flammable liquids. Such liquid pool fires are generally buoyancy-driven and emit a large fraction of their heat release in the form of radiation. Ignition and combustion characteristics of liquid pools depend on the design parameters such as diameter, spacing, and shape of the pools. This laboratory scale study was conducted to determine the effects of these parameters on the characteristics of multiple liquid pool fires. The measurements reported include pool surface regression rate, flame height, temperature, and concentrations of carbon dioxide, soot, and oxygen.
