Experimental determination of premixed laminar burning velocities for ethanol-air mixtures
摘要
Abstract
The constant-volume combustion vessel and high-speed schlieren visualization system were employed to experimentally determinate the laminar burning velocities of ethanol-air gaseous mixtures at various initial temperatures,initial pressures and equivalence ratios.An empirical formula was developed to estimate the unstretched laminar burning velocities by linear regression.Results show that the burning velocities first increase and then decrease with the increasing equivalence ratios,and the peak values of flame speeds appear at equivalence ratio of 1.1.The burning velocities decrease with the increase of the initial pressure,while the reverse holds with the initial temperature.The fitted formula shows good agreement with the experimental data,and hence it can be used for approximately calculating of the laminar burning velocity.关键词
