摘要
随着载人航天、深空探测的发展,越来越多涉及到探测器的天基发射,如同火箭(导弹)的地面发射,天基发射过程中同样面临着羽流扰动问题。在真空状态下,羽流不受约束地迅速自由膨胀,呈现与地面燃气流不同的流动特性,对于真空羽流导流流场,更是涉及到狭小空间的流动和多种壁面碰撞、反射等过程,羽流流动状态更为复杂。结合某项目羽流导流技术的研究情况,就CFD/DSMC耦合仿真方法在天基发射羽流导流技术研究中的应用进行了探讨。
Along with the development of manned space and deep space exploration, the detector space-based launch technology is developed. The impact of the plume exists in the process of space-based launching, as it does in the ground-based launching of missile. Plume expands freely in vacuum and shows different flow characteristic with the gas flow in ground-based launching. As in vacuum plume diversion, it is involved with small space flow, various wall collisions and inflection, the plume flow state is more complex. Based on the research of plume diversion technique for a project, application of the CFD/DSMC coupled simulation method in the research of plume diversion technique is discussed in this paper.
