| 1. | The air passage is called the air bleed . 空气通道叫通气孔。 |
| 2. | Reverse flow can be observed at the outlet when the chimney gap increased to a certain value 太阳能烟囱的空气通道宽度增大到一定数值时,可以观察到在太阳能烟囱出口处有明显的回流现象。 |

| 4. | A constricted throat in the air passage of a carburetor , causing a reduction in pressure that results in fuel vapor being drawn out of the carburetor bowl 文丘里管汽化器空气通道中的一段喉管,导致压力减小从而把燃料的蒸气抽出汽化器的碗状部分 |
| 5. | Experiment is carried out with air in tube of d = 44mm with twisted - tape inserts of y = 1 . 88 , 2 . 62 , and 3 . 81 . the parameters ranges are p = 0 . 1 ~ 0 . 4 mpa , t = 150 ~ 700 ? 试验段为套管,一次侧为空气通道,二次侧为冷却水通道,试验时沿试验段全长插入不同规格的扭带。 |
| 6. | The simulation was began based on defining the boundary which was coupled with heat and mass transfer . numerical simulation was performed with different inlet velocity , temperature , water vapor concentration and channel width 对于数值模拟的结果,采用后处理工具tecplot等进行处理,得到了一、二次空气通道内的压力、速度、温度以及水蒸汽浓度的分布图。 |
| 7. | Results showed that , for trombe wall solar chimney , there is an optimum ratio of chimney gap - to height to achieve a maximum airflow rate , which is dependent on the inlet design and independent of solar radiation 结果表明,对于trombe墙体式太阳能烟囱,存在可以获得最大通风量的最佳空气通道宽度与高度的比值,这个最佳比值是依赖于太阳能烟囱进口的设计,而与太阳辐射强度无关。 |
| 8. | However , for vertical roof solar chimney or inclined roof solar chimney with both ends open , either a large optimum gap - to - height ratio or no optimum chimney gap was found in the range of chimney gaps investigated 但是,对于带有竖直集热板或倾斜集热板屋顶式太阳能烟囱(其特点是两端完全开口) ,在研究范围内,或者得到很大最佳的宽度与高度的比值,或者没有找到最佳空气通道宽度值。 |
| 9. | Abstract : apply computer simulation to the distribution pattern of air - flow without considering the cold condition of the combustion and compare the flow patterns under different designed circumstances . and the effect of the design of the partition in the air way of the burner on the flow and mixture of gas and air is especially studied . the result shows that the design of partition plays a very important role in strengthening the mixture of gas and air , but increases the loss of the resistance in the air way and the total pressure of the air way in same working conditions needs increasing 文摘:应用计算机模拟的方法,在不考虑燃烧的冷态情况下,研究了热风炉燃烧室内的气流分布规律.在此基础上,比较了2种不同设计方案的气流流动特征,尤其是研究了燃烧器空气通道内阻流板的设置与否对空气和煤气的流动和混合的影响.结果表明,阻流板的设计对加强空气和煤气的混合有着极为重要的作用,同时也增加了空气管道的阻力损失,在同样的工况条件下需要提高管道系统的总压力 |
