摘　　要：从理论、实验和数值计算方面,阐述和总结了低温推进剂射流雾化的研究现状和进展。对射流雾化机理及形态进行了分类,重点从对比常温流体与低温流体射流雾化特征参数不同的角度,梳理了射流雾化方面的数值研究方法,并介绍了低温射流雾化的相关实验研究。结果表明:空气扰动破碎机理仍是最广为接受的理论,而超临界工况下射流雾化形态不符合现有的射流雾化分类;数值计算方法逐渐由流体体积法和水平集法向直接数值模拟转变,对闪蒸现象的建模是研究重难点之一;低温流体射流喷雾实验数据匮乏,需通过丰富测量手段,提高测量精度的途径获得完整、准确的实验数据。From aspects of theory,experiments and numerical simulation,the research status and progress of cryogenic propellant jet atomization were analyzed and summarized.The mechanism and patterns of jet atomization were classified,the numerical research methods of jet atomization were sorted out and relevant experimental study of cryogenic jet atomization was introduced by comparing different atomization parameters between ambient fluids and cryogenic fluids.It indicates that the air disturbance induced breakup mechanism is the most accepted theory,whereas,the jet atomization morphology under supercritical conditions does not accord with the existing classification.Numerical methods for jet atomization gradually change from the volume of fluid method and level-set method to the direct numerical simulation.Modeling of flashing phenomenon is one of the key points in the simulation.Furthermore,there lacks of experimental data of the cryogenic jet atomization.Enriching measurement methods and improving measurement accuracy can solve this problem.
