So, choose as far as possible to improve the nozzle of small high cutting speed and cutting quality is useful, but the nozzle at low altitude may cause double arc phenomenon.
Induced by the high-speed feed jet flow, the solid particles above the feed nozzle tended to flow down, and a reverse flow zone was formed along the riser wall.
受喷嘴区高速射流的影响,喷嘴上方固体颗粒呈向下流动趋势,形成一个诱导回流区域。

The scarfed nozzle is used in engines which can produce reversal thrust, or to produce revolving torque on turbine rocket engines at highspeed.
