(irregular flow of a fluid)
Turbulence (or turbulent flow)
is chaotic flow of a fluid.
It is characterized by changes in flow velocity
and pressure over space and time, and eddies,
i.e., circular or swirling flows, often lasting
only a short time.
In contrast, a laminar flow has the
fluid flowing in an organized fashion,
In astronomy, turbulence in Earth atmosphere
is a contributor to seeing issues.
It can be detected in gases, e.g., within stars or clouds,
through the analysis of spectral lines.
