Square pool fires with length of 5, 7.5, 10, 15, 20, 25 and 30 cm and rectangular pool fires with dimensions of 10 cm x 20 cm and 10 cm x 40 cm were burned in a wind tunnel, under a longitudinal air flow ranged from 0 to 3m/s with incremental change of about 0.5m/s. Methanol and gasoline were burned and compared, with results indicated that their burning rates showed different response to the longitudinal air flow. With the increase of the longitudinal air flow speed, the burning rates of methanol pool fires, except the 5 cm square one, first decreased and then increased, but those of the 5 cm methanol square one and the gasoline pool fires increased monotonously. The burning rate of smaller square pool fires increased more significantly than that of the larger ones, as well as the enlargement of their flame attachment length along the ground. The burning rate of a rectangular pool fire with longer rim parallel to the longitudinal flow increased faster, but the flame attachment length seemed to increase more gradually, with the increase of the longitudinal air flow speed than that perpendicular to.
在风洞中燃烧了边长为5厘米、7.5厘米、10厘米、15厘米、20厘米、25厘米和30厘米的方形池火以及尺寸为10厘米×20厘米和10厘米×40厘米的矩形池火，纵向气流速度范围为0至3米/秒，增量变化约为0.5米/秒。燃烧了甲醇和汽油并进行比较，结果表明它们的燃烧速率对纵向气流表现出不同的响应。随着纵向气流速度的增加，除5厘米见方的甲醇池火外，甲醇池火的燃烧速率先降低后增加，但5厘米见方的甲醇池火和汽油池火的燃烧速率则单调增加。较小方形池火的燃烧速率比较大方形池火增加得更显著，并且它们沿地面的火焰附着长度也增大。与纵向气流平行的边长较长的矩形池火的燃烧速率增加得更快，但随着纵向气流速度的增加，其火焰附着长度的增加似乎比垂直于纵向气流的矩形池火更平缓。
