- The effects of reynolds number , back surface of nozzle , aft - dome configuration and degree of submergence on aft - end internal flow were studied by both cold gas simulation and numerical simulation . it is showed that the separated flow is sensitive to the change of reynolds number and aft - end cavity configuration
最后，利用冷流模拟与数值模拟相结合的方法，研究了雷诺数、喷管背壁形状、后封头形状和潜入深度对燃烧室尾部流场的影响，结果表明流动的分离对雷诺数和背壁区几何边界的变化很敏感。 - This article has a particular research on three kind of gas / liquid coaxial nozzles for their flow performance and atomization performance under cold - flow - simulated experiment with the supply of laser doppler technology , and the measurement of the drop parameter and combustion performance under normal pressure and burning condition
本文应用激光多普勒技术对三种气液同轴模型喷嘴的流量特性和雾化特性进行了冷流模拟实验研究，并在常压燃烧条件下对其喷雾流的液滴参数和燃烧性能进行了实验测量。 - Experimental investigation described in the paper may contribute to the development of internal flow study in solid rocket motors . the result is not only conducive to understand the mechanism of aft - end internal flow , but also available for reference to the design of solid rocket motors . the detailed measurement data can act as data - base to verify the accuracy of numerical simulation
本文的冷流模拟工作对于固体火箭发动机内流场研究的发展具有一定的贡献，实验结果有助于提高对燃烧室尾部流动机理的认识水平，可以为发动机设计提供参考，也可以作为数据库来校验数值模拟的准确度。 - 2 . using cfd software - fluent , many flow states were been simulated . these states are the influence of nozzle structure with the flow , the distributing characteristic of inside flow , the influence of cold gas flow and outside flow with the work of the nozzle , the change of inside pressure load when the nozzle regulates
2 、借助cfd软件fluent ，计算出可调喷管本身结构对流动的影响、可调喷管流场的参数分布、冷却气流对喷管流动的影响、外流对可调喷管内流的影响、喷管的冷流流场和喷管调节过程中内壁面的压强载荷变化。 - Ptfe is one of the most corrosion - resistant materials in the world . however it has defects such as the hot expansion and cold contraction rate is10 times larger than that of steel and the original cold fluidity ( creeping ) etc . therefore , as temperature increases , ptfe extends so excessively that it would collapse and then block the flow of media ; as temperature decreases , ptfe contracts so excessively that it would be ripped and then cause leakage
Ptfe是当今最耐腐蚀的材料之一，可它被制造成衬里的时候，会存在热胀冷缩比钢铁十多倍及固有的冷流性等缺陷，致使ptfe衬里管道、设备，在使用过程中，温度高时， ptfe衬里层会伸长过多而内瘪，阻塞了介质流通；温度低时， ptfe层会收缩过大被拉裂而泄漏。
