air flow
Circulation of breath
Air flow is the movement of air through or around a space.
It describes how air circulates in ventilation systems, engines, or aerodynamic contexts: The building's air flow keeps temperatures comfortable, Poor air flow caused the engine to overheat.
Also spelled as one word: airflow.
