Abstract
This work aims to the numerical study of the laminar burning velocity of gasoline/air combustion by three different kinetic models from literature, and to observe the effect of adding methanol in these analyses. Numerical simulations were carried out over a wide range of conditions to compare the capacity of all three mechanisms in modeling the laminar burning velocity of a gasoline surrogate. All mechanisms showed a good approach to the experimental data from literature, although one of them had a substantial divergence of laminar velocity when the results were plotted in function of pressure. A ternary and five-components gasoline surrogates were compared and both produced very similar results. Also, the effect of increasing the concentration of oxygen in the oxidizer was investigated, and addition of 1% of oxygen resulted in substantially higher velocities. Finally, the methanol addition on gasoline only affects significantly the results in a rich mixture and high methanol concentrations, resulting in higher laminar burning velocities.
