现代喷气发动机结构已相当复杂,但其性能仍有许多不能令人满意之处,如沿流路压力损失大、部件效率低、压气机容易失速喘振、燃烧室容易过热震荡、再点火高度低、稳定工作范围窄等。本文讨论紊流旋涡现象,给出新推导的紊流动量方程,仿自然生态,提出减少旋涡损失,利用旋涡功能的设想,引出一些值得深入研究的问题。
The structure of a modern jet engine has been quite complicated. However, its performance is still unsatisfactory. For example, the pressure loss along the flow path is large, the efficiency of components is low, the compressor is prone to stall and surge, the combustion chamber is easily overheated and the ignition level is low , Stable working range and so on. In this paper, we discuss turbulent vortices, give a new derivation turbulent momentum equation, imitate the natural ecology, put forward the proposal of reducing the vortex loss and using the vortex function, and draw some questions that deserve further study.
