This study presents new adiabatic laminar burning velocities of diethyl ether in air, measured on a flat-flame burner using the heat flux method. The experimental pressure was 1 atm and temperatures of the fresh gas mixture ranged from 298 to 398 K. Flame velocities were recorded at equivalence ratios from 0.55 to 1.60, for which stabilization of the flame was possible. The maximum laminar burning velocity was found at an equivalence ratio of 1.10 or 1.15 at different temperatures. These results are compared with experimental and computational data reported in the literature. The data reported in this study deviate significantly from previous experimental results and are well-predicted by a previously reported chemical kinetic mechanism.
本研究展示了在平面火焰燃烧器上使用热通量法测量的二乙醚在空气中的新绝热层流燃烧速度。实验压力为1个大气压，新鲜气体混合物的温度范围为298至398K。在当量比为0.55至1.60的范围内记录了火焰速度，在此当量比范围内火焰能够稳定。在不同温度下，最大层流燃烧速度出现在当量比为1.10或1.15时。将这些结果与文献中报道的实验和计算数据进行了比较。本研究报告的数据与先前的实验结果有显著偏差，并且由先前报道的化学动力学机制得到了很好的预测。
