Research on Premixed Gas Detonation Wave Propagation Simulation Qualitative Modeling

借助定性仿真,建立预混气体爆轰波的传播定性模型,推理分析不同初始压力下,预混气体爆轰波传播速度,研究预混气体爆轰波爆轰过程中传播速度与初始压力的关系,且采用定量的实验验证定性的建模推理分析结果。结果表明,定性推理分析的结果与实验结果是一致的,即随初始压力的逐渐增大,爆轰波的传播速度逐渐加大。爆轰波传播定性建模推理分析对安全传输可燃性气体和管道阻火器的安全使用具有重大意义。

With the help of qualitative simulation modeling study of premixed gas detonation wave propagation law,the premixed gas detonation wave propagation qualitative model was set up.Under the different initial pressure conditions,quantitative experiments were used to verify the qualitative modeling analysis results and comprehensive analyzes the influence and change of the premixed gas detonation wave propagation velocity.The results approve that the qualitative reasoning analysis is corresponding with the experiments result,the velocity of detonation wave propagation increases with the increase of initial pressure.Qualitative simulation modeling study of premixed gas detonation wave propagation has great significance to the secure transmission of flammable gas and the safe use of pipeline fire arresters.
