stillair
Stillair is a term used to describe air that is essentially at rest or has negligible bulk motion. In everyday language and in scientific contexts, still air refers to environments where air currents are minimal, and wind speeds are close to zero.
In meteorology and indoor settings, still air arises under calm weather conditions, quiet nocturnal cooling, or
The presence of still air affects how substances move and disperse. Transport is dominated by diffusion rather
Measurements of still air typically refer to very low wind speeds. Common practical definitions place still
Applications and implications include ventilation design, where designers seek to avoid stagnant pockets of air, and
