Abstract
Laminar flame characteristics of the blends of acetylene and methanol were numerically studied at 0.1 MPa and 363 K. A model was adopted to do the simulations with the accuracy validated with published laminar flame speeds data of methanol and acetylene. Simulation results showed that the methanol addition into acetylene leads to the significant increase of laminar flame speed with the equivalence ratio corresponding the maximum value shifting to the rich side. The reasons behind were analyzed and found the thermal and chemical kinetic effects both contribute the laminar flame speed variation while the contribution of the diffusion effect can be ignored. Besides, the equivalence ratio shift is found to be closely related to the adiabatic temperature and OH concentrations.
