According to the analysis of the turbulent intensity level around the high-speed train, the maximum turbulent intensity ranges from 0.2 to 0.5 which belongs to high turbulent flow. The flow field distribution law was studied and eight types of flow regions were proposed. They are high pressure ...
Airflow is laminar, but when it comes into contact with buildings or other obstructions, it turns turbulent. We now examine the airflow past a rectangular “box” building (Fig.1). The elevation view shows how a wedge of high pressure is built up on the wall facing the wind (windward ...
In an environment that cannot meet the requirements of the human body for normal breathing, the air is filled into a high-pressure gas cylinder for human breathing. Certificate display Packaging and Shipping FAQ 1.How to get a prompt quotation of gas...

The introduction of pressurized air into the air bearing’s cylinder creates a true air bearing airflow effect around the piston. With as little as 5 PSI of air applied to the cylinder, the same air that drives the piston also produces a stiff circumferential cushion of air to support the ...
High Strength PP Plastic, Light Weight and Durable Product Description A solution for most kind of ducting ventilation system. ♦ Simple installation, simple maintenance. ♦ Ball bearing motor. ♦ Large air flow. ♦ High Pressure, high efficie...

▶ Built-in high pressure air assist nozzle: S30 series is equipped with advanced high-pressure air-assisted metal nozzle, which can generate high-pressure airflow under the air pump, greatly improving the cutting efficiency, and the cutting speed is more than 5 times faster than that without...
This failed to account for the effects of the flow on the upper surface of the plate where low pressures exist and from which a major portion of the lift of a wing is produced. The idea of air as a continuum with a pressure field extending over great distances from the plate was to ...
