摘要
本文在实验结果基础上讨论了锥-柱体跨声速飞行时物面上产生的侧体激波系。分析了波系分布随来流M_∞数的变化;讨论了波系形成与流场内部流动机制的关系,进而解释了波系形成原因;建立了波系的一种模拟方法。最后,阐述了侧体波系研究在实际应用中的重要性。
Based on the experimental results, this paper discussed lateral shock wave family generated on the surface of a cone-cylinder fiying at transonic speeds. Variation of the wave family distribution with free-stream Mach number M∞ is analyzed; The relation between the formation of the wave family and the flow mechanism in the flowfield is discussed, and reason for the formation of the wave family is explained 5 A method for simulating the wave family is established. Finally, it is elaborated that research on the lateral wave family is of importance in practical applications.
