容积式受限空间油气爆燃火焰特征的实验研究

根据容积式受限空间油气爆燃火焰特征实验研究的需要,设计了实验系统,进行了不同油气体积分数下的油气爆燃模拟实验。基于实验所得的瞬时火焰信号数据与火焰图像,分析了不同油气体积分数下容积式受限空间内油气爆燃的火焰形态结构、传播速度、强度与持续时间等主要行为特征,所得结果对探索油气爆燃机理与基本规律具有重要参考意义。

Experimental Study on Flame Characteristics of Gasoline -air Mixture Deflagration in a Confined Space

In order to meet the needs of experimental studies on gasoline -air mixture deflagration ,a corresponding experi-mental system is designed .By using this system ,a series of gasoline-air mixture deflagration experiments have been done under different volume fraction of gasoline .Based on the instantaneous flame sign and flame images obtained in the experi-ments ,the shape ,structure ,spread speed ,intensity and duration of the gasoline -air mixture deflagration flame are ana-lyzed .The results have significant values for the exploration of the mechanisms and laws of the gasoline -air deflagration .
