Experimental and kinetic study on the laminar burning speed, Markstein length and cellular instability of oxygenated fuels

•Laminar flame of PODE3, DMC and NB were studied using spherical flame method.•Laminar flame speed, Markstein length and cellular instability were measured.•The effect of fuel molecular structure on laminar flame propagation was evaluated.•PODE3 has the most stable flame and highest laminar flame speed among the three.
