气流

In the paper, the resistance heated and continuous facility is adopted to finish scramjet combustor experiment research on hydrogen-fueled and ethylene-fueled ignition and combustion at different equivalence ratio. The continuous clean airflow of flow ratio 0.73kg/s, total temperature Tt=1000K, Mach number M=2.0, total pressure Pt=0.8MPa is available to the inlet of direct-connected experimental model.

本文采用电阻加热的连续式实验设备，在燃烧室进口气流为高温纯净空气、Ma数M=2、总温Tt=1000K，总压Pt=0.8MPa条件下，进行了不同当量油气比的氢和乙烯燃料的超音速燃烧室直连式实验。

Surface spraying treatment was carried out on air flow distribution board made from low carbon steel to enhance its wearability and durability.

对普通低碳钢气流分布板进行表面喷涂处理，达到增强分布板耐磨性，进而提高分布板使用寿命的目的。

It adopts new type mesh belt conveying method, moves through sprocket-chain, avoids bottle dropping, breaking and falling. Because of big pitch design, it has advantages of small thermal capacity, high aeration, small influence to airflow. It is convenience to get rid of glass piece, conveys bottle smoothly.

采用新型的底带、侧带整体式网带，利用链轮链条进行运动，避免了由于底带或侧带跑偏或爬行引起的掉瓶、碎瓶与倒瓶现象，由于大节距的设计，具有热容量小、通风率对气流组织影响小、可及时排除玻屑、送瓶平稳等优点。

A 5 micron aluminum filter is located in the air stream to keep the drying chamber free from airborne particles.

The parameters of pulse combustor such asfrequency,length of feed tube drying tube effecting on drying property were analyzed.It ispropitious to dry high surface-water containing,small granule or liquid materials.

分析了脉动燃烧器频率、热负荷、干燥管长等参数对干燥性能的影响；发现脉动燃烧器尾管内干燥更适合于含表面水高的小颗粒物料或液体物料，可充分利用脉动气流和声波能的作用，使物料分散雾化，增大表面积，提高干燥效率；研究了脉动燃烧器尾管内干燥颗粒物料的传热特性，并将试验结果与其它类型的干燥器进行了比较。

The simulation result shows that during the dust collection process by impinging jets,two ...

模拟结果表明，对喷流除尘过程中，两股相向运动的含尘气流相互碰撞，使粉尘颗粒在撞击区来回振荡，形成高浓度区，从而增大了颗粒间团聚的机率，强化了粉尘的团聚效应，有助于提高除尘效率。
