Abstract

A new technique for measurement of mass flow rates in buoyant fire plumes is described. The characteristics of 10-200 kW methane diffusion flames stabilized on porous-bed burners of 0.10-0.50 m dia. are described. A transition in the dependence of flame height on heat input and burner size was observed when the flame height was about four times the burner diameter. The mass flow rates in the buoyant plumes produced by the fires were measured for a range of elevations starting just below the time-averaged top of the flame and extending to six times this flame height. The mass flow rates in this region of the plume were correlated by the use of a simple plume model. Atmospheric and forced disturbances in the air being entrained increased the entrainment rate of the plume.
