| Research Abstract |
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.
