On the base of above models and theories, three new kinds of bits, i.e. extended nozzle roller bit, self\|resonating water jet bit and combined jet and mechanical rock\|cutting bit, are developed.

当时 ，部分学者片面认为水射流的压力越高越好，日本研究出 170 0MPa的增压器，前苏联和美国研究出 56 0 0MPa的脉冲射流发生器。

In boiler field, proper atomization of high viscosity liquid fuel is the essential assurance to safe .stable and high efficient combustion for boiler; in the propulsion equipment of rockers and turbo jet-propelled engine, the atomization quality of liquid fuel is the precondition to improve combustion efficiency and supply sufficient propulsion; in the field of industrial manufacture, metal powder is made by liquid metal which is impacted by high velocity gas; in the field of agricultural irrigation, the water with certain velocity is used to strike metal disk to make insufflations proportionally to the irrigation field; in the technique of desulphurization and coal gasification, proper design of nozzle is the essential factor to advance the efficiency of desulphurization and coal transformation.

在锅炉领域，高粘度液体燃料的良好雾化是锅炉安全稳定高效燃烧的重要保证；在火箭推进装置、涡轮喷气式发动机中，液体燃料的雾化质量是提高燃烧效率并产生足够推力的前提；在工业生产领域，用高速气流冲击液态金属来制备金属粉末：在农业灌溉中，用一定速度的水流冲击金属圆盘破碎并改变方向实现对灌溉区域的均匀喷洒：在烟气脱硫、煤气化等工艺中，良好的喷嘴设计是提高烟气脱硫效率和碳转化率的重要因素。

In operation, the downhole devices will be laid down with tubings which will move up and down using the operation machine. Since the injection head can rotate in the determined speed, the rotating flow, compared with the conventional stable axial flow, can prevent the sands from depositing in the horizontal annular and washing the screen. The jet from high-efficiency jet nozzle will wash the screen directly with concentrated hydro-power. The working fluid can be clean water, without damage to the formation.

作业时用油管下入该井下装置，利用作业机带动油管上下移动，由于喷头可按照既定速度旋转，返回流体在水平段由常规的平稳轴向流动变为旋转流动，既可实现对防砂管的全方位解堵，又能避免砂粒沉积；高效喷嘴产生的射流直接对着防砂管冲击，能量集中；工作介质为清水，不会对地层带来二次污染。

A stream of water is shot under pressure from a large nozzle in a particular direction.

加压水流从一个大喷嘴朝特定的方向射出。

Nozzle flow was assumed to be frozen, and convective and radiative heat transfer from gas to solid wall was considered. Discretization of the governing equations was performed with two order upstream scheme, and radiative heat transfer equation was solved with Discrete Ordinates method. Absorption coefficient of water vapor was calculated by Leckner formula.

计算中，假定塞式喷管中的流动为冻结流动，考虑燃气向壁面的对流换热和辐射换热；采用二阶迎风格式离散控制方程，及DO模型离散求解辐射换热方程，水蒸气的吸收系数根据Leckner公式计算。

Nozzle, a very important part in high-pressure water-jet equipment, influences the other parts of the jet system.

高压水射流成套设备以喷嘴为中心，这是因为喷嘴是形成水射流工况的直接元件，它所造成的结果直接影响到系统的各个部分。
