Figure 2.

Comparison of laminar burning velocity (LBV) data for methyl decanoate (MD)-air mixtures at 373 K and 1 atm. Data from Sarathy et al.^[49], Seshadri et al.^[50], and Luo et al.^[51] were obtained using combustion kinetic mechanism models via Chemkin II simulation calculations. Error bars indicate the uncertainties in equivalence ratio and laminar burning velocity within this study.
