Measurements of Flat-Flame Velocities of Diethyl Ether in Air

This study presents new adiabatic laminar burning velocities of diethyl ether in air, measured on a flatflameburner using the heat flux method. The experimental pressure was 1 atm and temperatures of thefresh gas mixture ranged from 298 to 398 K. Flame velocities were recorded at equivalence ratios from0.55 to 1.60, for which stabilization of the flame was possible. The maximum laminar burning velocitywas found at an equivalence ratio of 1.10 or 1.15 at different temperatures. These results are comparedwith experimental and computational data reported in the literature. The data reported in this studydeviate significantly from previous experimental results and are well-predicted by a previously reportedchemical kinetic mechanism.
