The air conditioner forced draft fan ventilates the way to have longitudinal and the crosswise two kinds generally, the lateral ventilation the air current overflow sectional area is big, the wind speed is small, easy to create the big area the dead angle, but longitudinal ventilates the air current the overflow sectional area to be small, the wind speed is big, the dead angle area is very small.
冷风机通风方式一般有纵向和横向二种,横向通风的气流过流断面积大、风速小,容易造成较大面积的死角,而纵向通风气流的过流断面积小,风速大,死角面积很小。在使用条件许可的情况下,应该尽可能采用先进的纵向通风方式。

The theories on pyrolysis and coking and hydrogenation of heavy oil are used to know the liquefaction and gasify and coking of coal. 3. The results of particle feeding in the hot plasma jet (1) By using the cold state of spraying the diesel oil mist transversely in the air flow at the subsonic and ultrasonic speed to imitate the stress condition and motion trace of coal powder in the plasma jet, it shows that with the speed of air flow changed from subsonic speed to ultrasonic speed, the uniformity of mixture between the coal powder with certain speed and air flow becomes worse, mixture length becomes shorter, which agrees with the law of momentum transfer.
三、热等离子体射流中颗粒注入研究的结果(1)利用柴油油雾在亚、超音速气流中横向喷射冷态模拟煤粉在等离子体射流中的受力和运动轨迹,结果表明随着气流速度由亚音速向超音速增加,一定速度的煤粉与气流混合均匀度变差,混和长度增加,符合动量传递规律。

An analytical model was built up on the jet deflection in the crossflow by applying the theorem of momentum, which takes full account of mixing between the upstream fluid and burner jet, and of the total pressure difference between the two sides of the jets. Through analysis of this model, experimental study and numerical simulation, effects of the nozzle spacing ratio, width of the furnace corner, width of the nozzle and imaginary circle diameter on the aerodynamic field in the furnace were obtained.
本文综合考虑了炉内旋转气流与燃烧器射流的混合和燃烧器射流向火侧与背火侧的全压差等因素,应用动量定理建立了横向气流中射流偏转的分析模型,并结合冷态模化试验和数值模拟计算,得到了燃烧器间隙率、炉膛切角、喷口宽度和假想切圆直径等因素对炉内空气动力场影响的规律。

The temperature and density and direction of air masses can be determined, and thus the weatherman has historically offered predictions, but these predictions have become increasingly difficult, in part because of the Earth wobble which jerks the Earth about dunder her mantel of air, often at cross currents to the jet stream.
气团的温度、密度以及移动方向可以被确定,因此气象人员可以依据历史数据进行预测。但现在这样的预测越来越困难了,部分原因是地球晃动造成空气运行趔趄,风速带被横向交叉气流所干扰。

The decreased threshold shear velocity and unsaturated sand flows at the stoss slope of the dunes resulted the erosion at the toe of the dune. Under the medium and low drifting-sand winds the sands being transported have divergence with that on the surface, the mean grain size of transported sands is lower than that on the surface and the sand transporting is a stochastic process.
起动剪切速度减小与不饱和风沙流是沙物质在横向沙丘迎风坡坡脚不能产生沉积的主要原因;再者,平均风速并不能完全反映野外实际状态下气流的性质,在低-中强度的风沙活动过程中,被输送的沙物质的粒度组成与下垫面物质有明显的差异。

The field experiments on the secondary flow developed on the lee side show that there are strong sand transport potential at the lee side of the dunes near the surface because of the decreasing of the sand grain size and the other factors. The transport directions are nearly vertical to the dune trends. Those factors and the sand slumping on slip face, and the sand transport processes on the stoss slope make the transverse dunes maintaining their morphology under the advance processes.
对沙丘背风坡发育的二次流的野外观测表明,近地面一定高度内沙丘背风坡气流仍有一定的强度,由于背风坡的沙丘沙粒径较小等因素,背风坡气流仍保持一定强度的输沙率,输沙方向与沙丘走向基本上垂直,这种作用与沙物质向背风坡崩落、迎风坡的输沙过程等共同作用,因而使横向沙丘在运动中保持其形态。

The field experiments on the near surface airflow, sand transport rate, grain size of the dune sands and the morphology of the dunes show that though shear velocity decreased at the toe of the transverse dune, the threshold shear velocity decreased simultaneously. The decreased threshold shear velocity and unsaturated sand flows at the stoss slope of the dunes resulted the erosion at the toe of the dune.
对简单横向沙丘表面的气流、输沙率、物质结构,以及形态学特征的观测表明,在横向沙丘迎风坡坡脚尽管剪切速度有所下降,但起动剪切速度同时减小,起动剪切速度减小与不饱和风沙流是沙物质在迎风坡坡脚不能产生沉积的主要原因。
