The paper presents the results of measuring the propagation velocity and Markstein length of pure and inhibited laminar axisymmetric dimethyl ether/air flames using the PIV method. Their dependence on equivalence ratio and the concentration of inhibitor is studied. Trimethyl phosphate is used as an inhibitor. The measurement results show a strong dependence of the Markstein length on the concentration of the inhibitor. This suggests the use of this parameter as a measure of inhibition effectiveness of turbulent flames.
