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。

The research results provide theoretical basis and reference for the improvement of the efficiency and the structure optimization design of the deflectorjet servo valve.
