摘要

研究燃料液滴蒸发对提高燃油发动机效率、节约能源和减少排放至关重要。本研究利用超声驻波悬浮和高速摄像机等实验方法，研究温度和液滴特性（包括初始直径和成分）对蒸发过程的影响。实验记录了十六烷和柴油等燃料液滴在 150 °C 至 550 °C 的温度范围内的蒸发行为，液滴的初始等效直径为 0.10 至 0.30 毫米。蒸发率与温度呈正相关，十六烷和柴油液滴的蒸发率可能相差 15% 到 71%。

Experimental Study of Evaporation Characteristics of Acoustically Levitated Fuel Droplets at High Temperatures

Examining fuel droplet evaporation is crucial for enhancing fuel engine efficiency, conserving energy, and reducing emissions. This study utilizes experimental methods involving ultrasonic standing wave levitation and high-speed cameras to investigate the impact of temperatures and droplet properties, including initial diameter and composition, on the evaporation process. The evaporation behaviors of fuel droplets, like hexadecane and diesel, are documented across a temperature spectrum spanning 150 °C to 550 °C, with an initial droplet equivalent diameter ranging from 0.10 to 0.30 mm. The evaporation rate positively correlates with temperature and may vary by 15% to 71% between hexadecane and diesel droplets.
