The objective of this study is to discuss whether the flame buoyancy increases vent flows in fully-developed compartment fires. Vent flows of small-scale compartments with narrow frontages were measured. Different ceiling heights of the compartments were set to vary the work of flame buoyancy. Greater vent flows were observed under the conditions with high ceiling. Calculated vent flows were more consistent with experimental data when the effect of flame buoyancy was taken account in, compared with when it was not considered. It was concluded that the flame buoyancy had the effect on vent flows of these compartments.
