In the presence of the flowdeflector, 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。

Therefore, in the jacketed vessel, the reasonable spiral deflector on the one hand can flow the fluid which is in the jacketed vessel, it can heat or cool the materiel in the vessel better;
因此在夹套内合理设置螺旋导流板，一方面为夹套内的流体导流，能更好地加热或冷却容器内的物料；

The numerical simulation results show that the flow uniformity of catalytic converter with deflector is higher than that of the conventional catalytic converter.
