Air moves from high pressure regions to low pressure regions; (II) Air has inertia and, hence, changes direction only when obstructed (it does not always travel in straight lines); (III) Friction is developed when moving air comes in contact with surfaces and this causes the air stream to...
复数:airflows; 实用场景例句 全部 气流 气流产生的 The large eddy simulation approach is applied toairflowfield around buildings. 应用紊流大涡模拟方法对建筑物环境风场进行了数值模拟. 期刊摘选 The compressive effects ofairfloware great on the aerodynamics at high speed's flight. ...
26 In high-pressure systems, the mole cules inside the system move faster than those that surround it. The opposite occurs in low-pres sure systems, where the air inside the low is moving more slowly than in the surrounding area.Air flows around a high-or low-pressure system in much the...
When the large air quantity inflation is needed by a user, the striking part of the switching device is pushed inwards, and the air flows out of an air tap joint with large air quantity from a first air passage to a second air passage. When the high pressure inflation is needed, the ...
flow in curved tubes and turbulent flow. Different aspects of these flows tend to dominate depending on the flow speed orReynolds number. The concepts are integrated into a discussion of the overall flow versus pressure relationship over a wide range ofReynolds numbers. In addition, during forced...
The generated rotational flows are aligned in a uni-direction through scroll action, and the pressure rises accordingly. Since the exhaust outlet is reduced to focus air in a specified direction, these blowers are used for spot cooling. The static pressure is also high, which makes them a ...
1. Using unitary tank, compact structure with high strength. 2. Using double inlet forward centrifugal fan with large airflow, big air pressure and long drive distance. 3. The fan volute is made of plastic one-step injection molding with high efficien...
Pao2–Pao2 is normally less than 20 mm Hg but may be as low as 10 mm Hg in children and as high as 30 mm Hg in the elderly.15 Ventilation and Perfusion. Ventilation (V.) refers to the movement of a volume of air from the atmosphere in and out of the airways and is highly ...
the larger the pressure rise; the lower the velocity of flow, the smaller the pressure rise. Therefore there is a transverse pressure difference, and the airflow flows along the mesh screen to the side with low velocity. Therefore the position velocity of high velocity decreases, while the pos...
Wind is essentially air in motion, primarily caused by differences in atmospheric pressure. When air moves from high-pressure areas to low-pressure areas, we experience it as wind. Air, on the other hand, is a stable mixture of gases that envelops the Earth, composed mainly of nitrogen and...
