摘　　要：本文利用定容燃烧弹测量了初始压力0.1 MPa、0.3 MPa、0.5 MPa,初始温度298 K、373 K、453 K,当量比范围为0.8~1.6工况下的二异丙醚(DIPE)和甲基叔戊基醚(TAME)的层流燃烧速度,利用现有Creck机理进行验证,并优化得到了Modified Creck机理。对比机理预测值与实验值发现,Modified Creck机理对DIPE和TAME的层流燃烧速度的预测能力显著提高。通过敏感性分析和路径分析解释了Creck机理与Modified Creck机理预测能力的差异,分析了DIPE、TAME与甲基叔丁基醚(MTBE)的层流燃烧特性的相似性。In this paper,the laminar burning velocity of disopropyl ether(DIPE)and tert-amyl methyl ether(TAME)at initial pressures of 0.1 MPa,0.3 MPa,and 0.5 MPa,initial temperature of 298 K,373 K,and 453 K,and equivalent ratios ranging from 0.8 to 1.6 were measured in a constant volume combustion bomb.The Creck mechanism was validated according to the experimental results,and it was optimized by updating the underlying mechanism to obtain the Modified Creck mechanism.Comparing the predicted value of the mechanisms with the experimental value,it is found that the Modified Creck mechanism has significantly improved the prediction of the laminar burning velocity of DIPE and TAME.The differences in the predictive ability of the Creck mechanism and the Modified Creck mechanism were explained by sensitivity analysis and reaction path analysis.The similarity of laminar burning characteristics of DIPE,TAME and methyl tertiary butyl ether(MTBE)was elucidated.
