针对甲醇发动机冷起动困难的问题,基于单液滴方法研究了243~303 K低温下的甲醇液滴蒸发特性,并探索了环境温度、初始直径、燃料温度和进气流速的影响.结果表明:潮湿环境中甲醇的吸水性导致液滴蒸发过程分为纯甲醇蒸发和水主导的混合蒸发两个阶段,并且液滴寿命延长,液滴蒸发速率与环境温度也由指数关系转变为线性关系,导致低于263 K时液滴不能完全蒸发.提升环境温度整体上能促进甲醇液滴蒸发,当环境温度低于293 K时,将环境温度提高到293 K是促进甲醇蒸发的最有效途径.减小液滴直径对纯甲醇蒸发无影响,但会抑制液滴对水的吸收,从而提高了液滴平均蒸发速率.提高燃料温度增加了第二阶段占比,从而降低了液滴平均蒸发速率.进气流动对甲醇蒸发的促进效果随进气流速的增加而逐渐减弱,尤其当进气流速超过3 m/s时,促进效果提升程度微弱.
