项目摘要
Spray combustion is an indispensable technology for aero-space engines. The numerical simulation method is now being introduced for the development of advanced engines. The current spray combustion simulators, however, cannot describe the atomization of injected liquid fuel which is the most important process determining the subsequent combustion performance. In the this study, the new atomization concept derived from microgravity experiment observations were extendedly developed to reveal the self-destabilizing mechanism of high-speed liquid jet and the underlying physics of turbulent atomization. Using the new findings, we for the first time succeeded in developing a turbulent atomization sub-grid model, which can be integrated into the current spray combustion simulators to describe the local turbulent atomization feature experienced by the injected liquid fuel.
喷雾燃烧是航空航天发动机不可或缺的技术。现在正在引入数值模拟方法来开发先进发动机。然而,目前的喷雾燃烧模拟器无法描述喷射液体燃料的雾化,而雾化是决定后续燃烧性能的最重要过程。在这项研究中,从微重力实验观察中衍生出的新雾化概念得到了扩展,以揭示高速液体射流的自失稳机制和湍流雾化的基础物理。利用这些新发现,我们首次成功开发了湍流雾化子网格模型,该模型可以集成到当前的喷雾燃烧模拟器中,以描述喷射液体燃料所经历的局部湍流雾化特征。
