喷嘴

The method of characteristics was introduced to calculate the flow field after the primary nozzle exit, whilst Korst's recompression criterion was adopted to determine the corresponding cell pressure, and one-dimensional control volume method was employed to analyze the downstream flow field.

该方法采用特征线方法分析一次流喷嘴出口流场，结合Korst再压缩判据确定引射器盲腔压力，采用一维控制体方法计算第二喉道引射器的下游流场。

Driving parameters required for driving different types of nozzles are separately stored in a built-in memory unit of the recording head and in an internal memory unit of the recording apparatus.

In light of production practice, the author introduces some measures for reducing copper content of electric furnace slag to .8%: aplication of new type of concentrate nozzles, stabilization of flash furnace slurry, addition of coke powder to flash furnaces, control of the Fe/Si ratio of furnace slag, increasing the time for clarification of copper liquor, and addition of reductants, such as coal or pyrite.

结合生产实践，介绍了控制电炉渣含铜低于 0 。8%的几点措施：采用新型精矿喷嘴，稳定闪速炉炉浆；向闪速炉中添加焦粉；控制炉渣的铁硅比；增加铜液澄清时间；向电炉中加入还原剂煤块或黄铁矿等。

It was demonstrates by the simulations that the distributions of velocity and temperature was heterogeneous whether in the axial direction or on the cross section.Especially,it was also indicated clearly that gas and catalysts refluence and their temperature gradient exists"two apices"and the concentration of gasoline and diesel increases rapidly at the nozzle zone.

模拟结果表明，提升管内速度、温度无论是轴向还是在横截面上都存在明显的非均匀分布，特别是喷嘴附近，气粒回流严重，温度梯度存在双峰特征，汽油、柴油浓度迅速增长。

The feeding System of the heavy oil catalytic cracking unit with a capacity of 600,000 t/a in Shengli Petrochemical Plant was modified in order to meet the requirements of atmospheric residuum processing.

为了适应加工常渣的需要，胜利石油化工总厂 60× 1 0 4t/a重油催化裂化装置，对进料系统进行改造，采用UPC鼓泡型喷嘴和分段进料，改善了原料油的雾化效果，降低蒸汽的用量，改善了产品分布，提高汽油产率 3 。2 3 %、轻油收率 0 。63 %，提高经济效益 1 92 9.2万元/a。

Numerical Simulations of Flows in the Hartmann Resonance Tube and Ultra-Sonic Gas Atomization Nozzle;2. The gas flow in the Hartmann resonance tube was numerically investigated by the finite volume method based on the Roe solver.

采用基于Roe解法的有限体积法，对Hartmann共振管中的气体流场进行了数值模拟，研究了当喷嘴轴线处存在针型激励器的情况下流场的振动情况，数值计算的结果与理论和相关的实验结果符合得较好。

As such, this design is fine for static testing, but not recommended for a flight motor, where the rocket mass may rest upon the nozzle while sitting on the launch pad.

因此，这种设计是罚款的静态测试，但不推荐用于飞行汽车，而火箭的群众可能会休息后，喷嘴，而会议上发射架上。
