A Prediction Model of Pool Fire Flame Morphological Characteristics in Three Sidewalls Enclosure Structure Under Ambient Wind
Series of experiments on the combustion of pool fire within a three sidewalls enclosure structure under ambient wind were conducted to investigate the variation of flame morphology with wind velocity.The results indicate that the maximum flame height and flame trajectory length of pool fires within the confined structure show a constant or increasing trend with wind velocity.Comparing the experimental data with previous predictive models,it is found that the previous models could not accurately describe the variations of flame geometry.Through physical model and dimensionless analysis,the coupling effect of sidewalls and ambient wind on flame geometry of pool fires was investigated and the prediction models of flame height and flame trajectory were proposed in this paper.
