In the presence of the flow deflector, the generating of the vortices and the separating of the shear layer are avoided thereby the energy loss of the jet nozzle is reduced considerably. 由于喷头中有了导流体,避免了涡流的产生与剪切层的分离,从而大幅度地减少了喷头的能量损失。
And then, through a practical example, give the discussions on the problems such as the influences on the small-wave-transients by deflector motions and how to adjust to jet numbers corresponding to the load changes etc. 并通过工程实例,对折向器在小波动过渡过程中的影响、喷嘴如何随负荷变化而切换等问题作了分析与探讨。
