To understand the effects of gap width between nozzles on linear plug nozzles performance, three plugs with different wide gaps were brought forward, which were fixed on the same inner nozzle.

为了了解内喷管间隙宽度对线性塞式喷管性能的影响，提出了对应着同一个内喷管的三种不同间隙宽度的塞锥。

At least one second nozzle tube is fluidly connected to the fuel source and spaced radially outward from the first nozzle tube with a proximal end fixed to the flange.

至少一个第二喷嘴管与燃料源流体连接并从第一喷嘴管向外径向分隔开，并且该第二喷嘴管的近端固定于法兰。

It was found that the tabs fixed on C-D nozzles also enhanced the jet mixing distinctly, although the boundary layers of the jets from C-D nozzles were greater than that from the convergent nozzle.

结果表明，对于收扩喷管，虽然其速度边界层厚度明显大于收敛喷管，但加装小突片结构也能够明显的强化射流的混合。
