The movement of air, especially as it passes through or around something like a building, engine, or computer.
Compound of 'air' (from Old English 'ærest') and 'flow' (from Old English 'flowan'). The term became common in the 20th century with engineering and aerodynamics.
Engineers obsess over airflow because tiny changes can make a fan 30% more efficient or a car 5% faster—it's why Formula 1 teams spend millions designing the shape of air scoops.
