摘要
本文叙述了力学所激波管实验室建造的魔洞型单脉冲激波管的结构尺寸,气动特性及测量系统,使用证明这套单脉冲激波管装置是成功的。本文提出了关于魔洞作用机制的一个简单模型:对入射激波而言,魔洞的作用相当于低压室入口处有一膨胀段;对反射激波而言,魔洞的作用相当于一个有流动的分叉管。
The performance and construction of a magic hole sin-gle pulse shock tube and its measurement system are described.Thisfacility has been used in the studies of the chemical kinetic of TiCl_4 inour laboratory.The role of the magic hole is investigated and a simplemodel is put forward, i.e.,for the incident shock the operation of themagic hole is equivalent to an expansion section connected to the downstream of the diaphragm,in the other hand for the reflected shack themagic hole is operating as a flowing side branch.
