摘　　要：随着高超声速飞行器的发展,未来高性能动力装置的燃烧室温度和压力将越来越高,当燃烧环境达到超临界时,液态燃料的蒸发和燃烧过程将涉及高梯度传热传质和临界相变等复杂因素,使得雾化、蒸发和燃烧规律发生改变。本文对燃料液滴在超临界环境中蒸发和燃烧的相关研究进行了综述,总结了已有的重要研究成果,阐述了研究中急需解决的关键问题,为后续深入研究提供参考。With the development of hypersonic aircrafts,the temperature and pressure of combustor would significantly increase for high-performance engines in the future,and the supercritical condition will gradually appear in the engine combustor.As the combustor environment reaches to a supercritical condition,the critical phase transition,high-gradient heat and mass transfer will appear,thus leading to different processes of fuel injection,evaporation and combustion from ones under the normal condition.Therefore,an overall related research review about fuel droplet evaporation and combustion in a supercritical environment is provided in this study.Significant results to date are summarized and challenges for subsequent study are clarified,which may be helpful to the further exploration in this area.
