Birds and mammals are on extreme ends of the airflow spectrum. Mammals inhale oxygen-rich air and they exhale depleted air, exhibiting a so-called tidal flow pattern. In contrast, bird breath travels ...

A single-pass airflow pattern, or reduced pass airflow patterns, strive to minimize the airborne particulates in the space to reduce the risk of health care-acquired infections. Displacement ...

Caves across North America and Europe exhibit a breathing effect. This phenomenon is driven by physics, specifically ...

Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere. Scientists at the Research Unit ...
