The effects of dilution with nitrogen and steam on the laminar burning velocity of methanol at room and elevated temperatures

► We investigate the influence of N2 and H2O dilution on methanol burning velocity. ► Chemical kinetics calculations of ul agree well with heat flux method measurements. ► For both diluents the chemical effect is negligible for diluents ratios below 20%. ► A correlation for the thermal effect of several diluents on ul is proposed. ► The temperature exponent α is shown to reach a minimum for ϕ = 1.2.
