Turbulence is irregular fluid motion with interacting velocity fluctuations over a range of scales. It can mix a particle suspension and promote fluid entrainment into a turbulent plume.
A circular turbulent round jet supplied with kinematic momentum flux but negligible buoyancy flux conserves . A top-hat plume model and constant Batchelor entrainment give . From a point source with zero volume flux, , radius , and axial velocity .

Turbulence refers to the chaotic, irregular motion of fluid (gases or liquids) that is characterized by vortices, eddies, and rapid changes in pressure and velocity. It contrasts with laminar flow, where fluid moves in smooth, orderly layers. In different contexts, turbulence can be described as follows: 1. **Physics and Fluid Dynamics**: In fluid mechanics, turbulence is seen when the Reynolds number—a dimensionless quantity that predicts flow patterns in different fluid flow situations—is high.
