The phrase "air direction" is correct and usable in written English.
It can be used in contexts related to meteorology, aviation, or HVAC systems to refer to the movement or flow of air.
Example: "The air direction indicated a strong wind coming from the northwest."
Alternatives: "airflow" or "wind direction".
To show growers via field demonstrations, workshops and conference presentations how to monitor pesticide use, air direction and droplet penetration.
Two design cases differing in inlet air direction and flow rate, and two functioning modes, batch and continuous, were analysed.
The ventilation system controls are the near-ideal three-knob setup — one for air temperature, one for fan speed and one for air direction — though the cluster of indistinct buttons surrounding the audio display can be frustrating to operate.
The results of simulator and experimental data showed that the new system had the higher uniformity in the cooling of fruit as compare with the traditional system so that the packages located along the cold air direction received the equal airflow rate.
Our results showed stronger, statistically significant correlation (p ≤ 0.05) between high Cladosporium spp. spore concentration and air mass direction compared to the local wind direction.
The local Nusselt number decreases along the air flow direction, but fin efficiency increases in general.
Through calculation, it is discovered that the best length of the air flow direction for the present dehumidifier is about 0.3 m.
We found the influence of the expansion angle of the inlet and the front air channel direction on the micropump characteristics.
It was also found that natural gas spraying to the surroundings had better effect than that spraying along air flow direction.
Moreover, the inversion of the air flow direction between the operating stages is not needed to achieve suitable levels of dehumidification, enabling a design simplification.
The effects of curvature, laminate stacking sequence, air flow direction and boundary condition on the supersonic flutter characteristics of laminated composite cylindrical shell panels are investigated.
