撞击式喷油器结构简单，雾化效果可靠，被广泛应用于液体推进领域。流场涉及一系列复杂的时空演化过程。为了理解撞击射流雾化的基本物理原理和发展定量预测，人们做了大量的工作。本文综述了这一方向的最新进展，包括最新的理论、实验和数值研究，以及具有代表性的结果。最后，结束语解决了剩余的挑战，并强调了高保真模拟的建模能力。(三)2018中国航空航天学会。爱思唯尔有限公司制作和主办。
Impinging-jet injectors are widely used in liquid propulsion applications, since their simple configuration provides reliable and efficient atomization. The flowfield involves a series of complicated spatio-temporal evolutions. Much effort has been directed toward understanding the underlying physics and developing quantitative predictions of impinging-jet atomization. This paper summarizes the recent advances in this direction, including state-of-the-art theoretical, experimental, and numerical studies, along with representative results. Finally, concluding remarks address remaining challenges and highlight modeling capabilities of high-fidelity simulations. (C) 2018 Chinese Society of Aeronautics and Astronautics.
