Abstract:

The effect of the fire size on radiative heat loss fraction and combustion efficiency was examined by an analysis of scale for pool flames with varying diameter (D). Correlations between D and radiative heat loss fraction or combustion efficiency were obtained. For 0.1m < diameter < 1m, radiative heat loss fraction and combustion efficiency are relatively constant and independent of D. For larger pool diameters, radiative heat loss fraction decreases with increasing D.
