1·The impinging jet injection device improves combustion efficiency. If the fuel streams impinge with the airstreams directly at the exit of air-inlet, it makes negative effect on combustion efficiency.
燃气射流与空气流在进气道出口直接撞击不利于燃烧效率的提高。
2·The effects of fluidization number, injection velocity, particle mean diameter and static bed height on jet fluctuation are discussed.
研究了流化数、射流初始速度、颗粒平均粒径及静态床层高度对射流脉动特性的影响。
3·Based on the theory of indirect injection abrasive water jet, experiments on abrasive water jet rust-removing system have been studied.
本文利用后混合磨料射流的工作原理进行了磨料浆液除锈系统的试验。
4·The single tube respective jet grouting, enlarging nozzle diameter and specific slurry injection technology are proposed.
提出采用单管分喷工艺、增大喷嘴直径以及特殊注浆工艺等方法。
5·The rotational jet and local oxygen enrichment can improve the mixing of oxygen and pulverized coal, but the effect of coal injection is weak on the whole flow field in blowpipe.
结果表明,氧-煤喷枪的漩流、富氧率等仅在氧枪出口的有限区域内对流场有较大的影响;
6·When the jet is injected at negative injection angles, it disarranges the flow upstream and the curvature of jet trajectories varies smartly along the flow direction.
射流反向倾斜入射,对上游流场的扰动增加,射流在弯曲段内曲率变化大。
