Determination of Laminar Burning Velocities of Nitro-methane using Heat Flux Method

Abstract: In this paper the laminar burning velocities of nitromethane, ethanol and nitromethane-ethanol mixtures has been determined by using heat flux method. The laminar burning velocity of ethanol was measured at atmospheric pressure, initial temperatures range 298-358 K and equivalence ratio 0.7-1.6. The flame speed of ethanol shows a satisfactory agreement with previous available data. The burning velocities of nitromethane and mixtures were determined at 338-358 K. The burning velocities of nitromethane and nitromethane-ethanol mixture have not been investigated before. Therefore a comparison between these results and ethanol results was performed at different temperatures. All the results for nitromethane have same curvature behavior and maximum velocity for each temperature found at φ=1.2. The temperature dependence of ethanol and nitromethane with laminar flame speed has been studied. This research gives new experimental data for the burning velocities of nitromethane. The results have good correlation between them but the further experiments and model development is required to validate the results.
