An experimental study of the heat transfer to a ceiling surface exposed by natural gas flames in the range of 2.9-10.5 kW is reported. The gas temperature below and the total heat flux to the stagnation point were found to be functions of the ratio of the ceiling and flame height. In the continuous and the intermittent flame regions the stagnation point heat flux was found to be higher than reported earlier by You and Faeth, but to approach their results in the plume region. The heat flux from the ceiling jet to the ceiling agreed well with the earlier results.
