Abstract

A modified model of Lefebvre lean blowout fuel/air ratio containing humidity ratio was proposed based on cold flow field numerical simulation and analysis of humidity ratio effect on the combustion load parameters, combustion reaction and fuel atomization of piloted vaporization flameholder, under the conditions of 300-483K incoming temperature, 0.14-0.3 incoming Mach number and 0-0.16 humidity ratio. The effect of humidity ratio on the lean blowout performance of piloted vaporization flameholder was discussed. It was found that the combustion loading parameters increased with the increase of humidity ratio, and the lean blowout fuel/air ratio increased significantly with the increase of humidity ratio. Therefore, the combustion loading parameter makes it difficult to describe the change of lean blowout fuel/air ratio itself alone, and the effect of humidity ratio on the fuel atomization can not be ignored.
