Arabic term (edited): سلوك الهواء الطبيعي

Airflow, or air flow, is the movement of air from one area to another. The primary cause of airflow is the existence of air. Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude, temperature, and composition.

The flow of air can be induced through mechanical means (such as by operating an electric or manual fan) or can take place passively, as a function of pressure differentials present in the environment.

Airflow in buildings

In building science, airflow is often addressed in terms of its desirability, for example in contrasting ventilation and infiltration. Ventilation is defined as the desired flow of fresh outdoor supply air to another, typically indoor, space, along with the simultaneous expulsion of exhaust air from indoors to the outdoors. This may be achieved through mechanical means or through passive strategies (also known as natural ventilation).
