The phrase "air draft" is correct and usable in written English.
It can be used in contexts related to shipping, aviation, or architecture, referring to the flow of air or the draft created by air movement.
Example: "The air draft in the cabin was uncomfortable, prompting the crew to adjust the ventilation system."
Alternatives: "airflow" or "air current".
Another aspect that needs to be considered is the air draft.
It predicts the temperature and velocity and kinetic power of the emerging air draft for some chosen values of other parameters.
A concept without a fan, here called a fan-less concept, would give several advantages; no noise, no power consumption for the fan and increased comfort with reduced air draft in the room.
The model also shows the proportion in which absorbed solar energy is divided into different forms, and hence predicts the dependence of kinetic of emerging air draft upon dimensions of the chimney and properties of materials used.
Its lay-out (featuring a metal-net basket to contain the fuel and a chimney to force a natural air draft) allows a mix of combustion/gasification of the biomass occurring in a completely burning fire, appropriate for cooking tasks.
Furthermore, most objects captured in our trawls (e.g. broken fragments of hard plastic objects, nets and ropes) exhibited no or very little air draft when placed in seawater, and many objects sighted during the aerial expedition seemed fully submerged.
Many of the early designs failed to recognize the need for air drafts.
An investigation was conducted to develop ventilation systems to prevent cold air drafts during the winter season and create a suitable atmosphere inside the broiler rearing building.
In these furnaces, covered pots for glass melting were placed on a middle level slightly below the ground, and an underground tunnel brought in high-velocity upward air drafts.
The most common ways to improve animal movement were: (1) install a lamp on a dark race entrance, (2) move ceiling lamps to eliminate sparkling reflections, (3) muffle air hissing, (4) install shields and solid sides on races to prevent animals from seeing moving people up ahead and (5) eliminate air drafts that blow in the faces of approaching animals.
Aware that air drafts cause molten iron to glow white hot, he became convinced that air blown through molten iron not only would remove the carbon but also would cause the temperature of the molten mass to rise, making further heating unnecessary.
