Experimental studies are conducted on extinction of non-premixed dimethyl ether (DME) flames stabilized in the counterflow configuration. Studies are carried out by injecting a fuel stream made up of fuel and inert gas (N_2 or CO_2 or Ar or He) from one duct an oxidizer stream made up of O_2 and inert gas (N_2 or CO_2 or Ar or He) from the other duct. Critical conditions of extinction are measured by increasing the flow rate of the counterflowing streams until the flame extinguishes. Numerical studies are also performed using detailed chemistry at conditions corresponding to those used in the experiments and compared with measurements. The present study highlights the examination of the influence of equilibrium flame temperature, flame structure and kind of inert gas on extinction properties of DME. Results are compared and discussed in terms of Lewis number effect.
