turbulence kinetic energy

Turbulence kinetic energy (TKE) is the measure of the energy contained in the chaotic, swirling motions of a fluid, such as air or water. It reflects the intensity of turbulence, which involves unpredictable, irregular flow patterns. Essentially, TKE quantifies how much energy is present in the small, rapid motions within a turbulent flow, contributing to mixing, heat transfer, and momentum transfer. Higher TKE indicates more vigorous turbulence, influencing weather patterns, aircraft performance, and fluid systems, while lower TKE suggests smoother, more stable flows.
