Abstract
To investigate the influence of ceiling height on the combustion process of a pool
fire whose flame impinges the ceiling, a sequence of pool fires with varying ceiling heights was performed using a scaled-down cone calorimeter. N-heptane and jet-A were employed as fuels to conducted the tests. Experimental findings reveal that with the decreasing ceiling height, the maximum and average heat release rates will initially increase due to the enhanced heat feedback, and then decrease as a result of the restriction of air entrainment caused by the extremely small ceiling height. In addition, the dimensionless ceiling height is found to have a linear relationship with the logarithm value of the dimensionless averaged heat release rate for the two given fuels with the similar slope of -2/3.
