| dc.description.abstract | Mean temperatures were measured along the axis of propane gas flames using a porous ceramic burner. Data for fire heat release rates ranging form 13.3kW to 30.6kW were taken and analyzed. It was found that the lower zone of a fire in a clam environment could be conveniently divided into three regions. For the same heat release rates, the fires were subjected to a cross flow of 0.72ms-1 and it was found that along the axis, the three zones could be identified. The excess temperature in the intermittent zone decreased with height to the power of 0.60 for the calm environment and 1.11 with crossflow. In the plume zone, excess temperature decreased with 1.87 power for the clam case and 2.05 with crossflow case, all data when plotted on log plots fell on a single curve | en |
