摘      要：An experimental study was carried out to investigate the flame characterization and temperature profile for single and multiple pool fire with the influence of cross *** were 13 test cases in total,categorized into circle and rectangle fuel pans,with diameter(or equivalent diameter)ranged from 50 mm to 300 *** was used for the fuel of pool *** K-type thermocouples were arranged around the flame to monitor the flame temperature,while the flame tilt angle was measured based on the photograph of flame for different ***,it can be found that there are three phases,including preheating,steady burning and extinguishing phase,during the flame *** maximum temperature near the fuel surface is~1040 K,which is higher than that of flame plume(~600 K),in the steady burning phase of circle single pool fire(D=300 mm),while the average burning rate is~1.525 g/*** addition,the burning rates of all cases were measured and compared with the current predicted ***,the flame morphology of single/multiple pool fire at different cross wind speed(ranging from 0 to 3.5 m/s)was analyzed,and it is found that the results for single pool fire agree with Thomas model and AGA model well,which are not suitable for multiple pool ***,the temperature profile of different case was measured with various wind speed.
