airflow

This term describes the physical movement of air, carrying a technical connotation that suggests a controlled or measured stream. It is most frequently employed in engineering, architecture, and aviation to describe how air interacts with a structure or moves through a ventilation system. The word evokes a sense of efficiency and direction, focusing on the mechanics of gas dynamics rather than the subjective feeling of a breeze.

As an uncountable noun, it refers to the general phenomenon of air movement. It does not have a plural form in standard usage; one does not refer to multiple airflows in a single system, but rather to the volume, velocity, or quality of the airflow. To quantify it, speakers use partitive expressions such as a stream of airflow or a pattern of airflow.
