abstract = {The evaporation of fuel droplet groups in the combustion chamber of aero engines is frequently influenced by droplet interactions; yet, it is challenging to describe the evaporation state of droplet groups based on the evaporation characteristics of individual droplets. Therefore, it is necessary to carry out experimental research on multi-droplet evaporation to explore the evaporation mechanism of multi-droplets. Firstly, an experimental platform was built and the evaporation experiment of two droplets and three droplets of aviation kerosene/glycerin arranged in a straight line was carried out by the hanging drop method. Then, combined with the theoretical and experimental data of droplet evaporation, the droplet evaporation model was established. The findings demonstrate that the rate at which numerous droplets evaporate increases as droplet spacing increases, approaching the rate at which single droplets evaporate. The evaporation rate and droplet spacing have an exponential relationship, and the overall accuracy of the model is high. In conclusion, the experimental data obtained from the experiment and the proposed droplet evaporation model effectively supplement the research content of multi-droplet evaporation characteristics,which has positive significance for the study of droplet group evaporation characteristics and the design of aero engine combustion chambers.}
