Abstract
In this research experimental measurements of adiabatic burning velocities in methane-air and propane-air flames were carried out over a wide range of equivalence ratios at atmospheric pressure. Heat flux method was used for measurement of burning velocities. Experiments were done for methane-air and propane-air mixtures at various equivance ratios.The maximum burning velocity for methanr-air and propane-airwas obtained at equivalence ratio of 1.1 as 37.33 and 42.1cm/s respectively.The results were in satisfactory agreement with published data in the literature. Simulations were performed using Premix code of ChemkinII with GRI Mech3.0 and Princeton university reaction mechanisms for the combustion of methane and propane respectively. The simulation and experimental results also showed good agreement
